LS6 Valve Springs on SBC Vortec Heads

How to check and install LS beehive valve springs on Vortec heads + check for max lift!
Ls6 springs work great for mild roller cams!
An easy at home way to check your spring height and spring to retainer clearance at home, no special tools needed (other than a caliper)
I do own a valve spring micrometer but this method works for guys that dont
Beehive Springs offer great valve control/performance and require no expensive machining to work on vortec heads.
*Stock vortec springs are only good for mild roller cams under approx .430 lift or mild flat tappet cam or

Dude! Why do you not have more VIEWS! This is an amazing video! You have a good clear way of explaining all of this and for the FIRST time, I understand lift - You have a new sub - I hope you can grow your channel!

Thanks man I really appreciate that! I have alot of cool projects on the go and finally decided to start filming some of it. There is alot of weird info out there so I'm trying to make videos that I wish i had a few years back when I needed info. Please share my videos and hit me up if you need any help or parts for your vortec projects!

[@donaldwarwick6780]

@@cuttersperformance Thank you for sharing!!! I just did my first top end rebuilt on my 1970 chevelle crewcab. I used Vortec heads on the 307 bottom end. I have a 350 in the garage and I wanting to use my vortec heads on them with a nice cam - but I don't want to machine the hell out of them. With this information, I can get springs and put a nice cam in it and really go to town! Keep up the content - you actually explain things so that EVERYONE can understand. I am learning all of this and have been lost. There is a guy locally who I met on the SBC board on Facebook and he has been an awesome GURU for me as well! You are right there is not only so much misinformation but also nasty people who get hateful in a second if you don't grasp the concept they are poorly explaining. So, I tip my hat to you - and I will share your content with everyone I can.

I'm going to totally agree with this statement. And I have over 20 years experience building high performance engines, and so I also know what to look for when people make videos about a specific subject. I'm also the type that will call out somebody when they're just trying to get views but don't really know what they're talkin about. While there would be a couple of things I would add, this video is quite good and quite informative, and also explaining things in a clear way for others to understand. I can only imagine who gave it thumbs down. But then again it seems like every good video has thumbs down but nobody comments on why. Anyways this is a very misunderstood subject and very rarely do I see people cover it this clearly. I'm definitely impressed.

[@michaeldose2041]

I agree that this is an excellent vid. The reason there aren't more views is because these engines are obsolete. LS is the budget build of choice now and the next generation LT has been out for quite awhile now. The LT will replace the LS and will only gain momentum in the coming years.

One thing to note, I did not see you cover in either video. I watched two of your video's on this topic you put out. You can run harden valve lash caps to get the needed stem height for the self aligning rocker arms. Just something to add I know a lot of people shy away from running them but they do work, also yes I know I am commenting on a 3 year old video just figured I would add this for those that did not know.

I just pulled my pressed in studs on 906 vortec heads. I used anti seize grease to lubricate the nut on the stud being pulled . if the nut starts getting hot move to the next stud and let that one cool off. It looked like most of the studs are stake and were difficult to pull and a couple came out easy. do not use a cheap nut use a valve stud nut which is hardened.

Someone mentioned to me that they had seen a KZbin video about swapping to complete LS valve train. I don't remember, they said they were the 1.99" intakes and 1.55" exhaust. Upgrading to a bronze 1/2" odd guide for the .312" valve stem, as well as the LS6 springs. I haven't found anything on this. I've found plenty of videos, swapping springs. Yours is the most comprehensive on the spring swap. But I'm wondering if there is any advantage, performance-wise, flow-wise or weight-wise with that kind of swap. All I know is is from what I've been finding in researching, is that the stock 1.94s and 1.50s are pretty much better off left alone rather than going to a 2.02 and 1.60. Have you ever seen or heard about anything about the valve & spring swap (and guide) upgrade?

SCREW IN STUDS A MUST!

[@chrisfox2758]

Hey I was told and many write ups online using ls6 springs and comp cam retainers 767-16 u could run a lt4 hot cam so what you are saying is even with the ls6 springs and retainer u can only still get a max lift of .480 with 1.5 rockers

[@cuttersperformance]

You will have to check on your heads but you will find that running the 787 on vortec heads won't give you the proper spring installed height with stock keepers That will two things: 1) Your valve spring just went from a max lift of say .550 with a 1.800 installed height to a max lift of .500 installed at 1.750. 2) your seal to retainer clearance with proper safe clearance will only be around. 480 maybe .500 with stock seals. So Basically no matter how you do it with stock keepers and Ls6 springs past .500 lift you are pushing the limits. Will it work slightly past .500 with stock keepers...maybe but is it worth the risk? You will have to do the measurements on the heads, you can use the method shown in the video without having to but any special tools Let me know if you have any questions

Hi, will these Beehive Springs work on my 1999 Dodge 5.9l 360 Magnum Gas Engine..??.. I plan on buying all parts needed for my Cylinder Heads setup real soon.. Itself will stay mostly OEM with Porting the Heads.. Tanks...

[@jasonbuben2653]

Can you use factory retainers with the beehive springs and offset keepers

[@cuttersperformance]

No the 787-16 retainers must be used with the beehives

[@logicalspark3496]

How high of rpm can you rev if you put all the parts in? I have a former step-dad that has a 355 with the smaller valve vortec heads. He can only rev it to 5200 now

[@cuttersperformance]

These springs work with flat tappet cams and mild roller cams, ive used them at 6500 rpm no problem with a 1.94 valve

[@logicalspark3496]

@@cuttersperformance would the offset keepers work good to?

[@cuttersperformance]

@@logicalspark3496 yeah you need them to get the 1.800 installed height

[@logicalspark3496]

@@cuttersperformance does it still make power at that high of an rpm.

[@cuttersperformance]

@@logicalspark3496 yeah depending on cam

[@Mike-bn4zs]

Are there any other keepers I could use? All the 99095-1 keepers are sold out

[@nickolausvassallo744]

This video is very helpful I tried to purchase one of your kits but you said you do not have any available as of now. I just have one more question if you decide to cut down the valve seal guide with comp cams tool 4726 for even more lift how much would you have to take off ?

[@joe-hp4nk]

Just grind the guide down and put umbrella seals on the valves.

[@blownaway4371]

What about using Lash Caps?

[@hillsidesavage1413]

What’s the part numbers for this build sir?

[@lad63bird]

are those keepers comp cam 11/32 .050? or another brand ? what is the part number on them I need to know if they are 7 degree and the diameter if you know it? Many Thanks

[@juliodiaz8280]

Back again. Summit lists the gm 12499224 springs at .570 max lift. and the gm 12713365 at .550 max lift. Are these springs identical? Other places have the gm 12499224 at .550 max lift. Can I buy either springs?

[@2stage90]

I checked your stuff on the same head and your right. Do you know where you got those offset keepers? Thanks

[@cuttersperformance]

I will be getting more stock soon if your interested in some keepers and valve seals for vortecs

[@erinboursaw2083]

I got a l31 crate motor and I am pretty disappointed with it I wasn't expecting much but still not alot of power I want a 480 480 cam should I use that offset keeper to be on the safe side

[@rubengonzalez620]

Crate motor, it probably has the later Mexico made vortec heads, not nearly as good as the made in the US ones.

[@juliuscullum6596]

Do you have a part number for the off set keepers?
