I’m in the process of rebuilding my 454 right now and I’m super impressed with your videos. You sir are very gifted and a natural for teaching. Thanks so much for doing this.

[@2carpros]

Wow, thanks! And thanks for watching Garry!

[@mahdistasalman571]

The transformation is unbelievably good.

[@2carpros]

Thanks for watching!

[@drakerichardson3162]

Your videos are great. One thing to note that may help others is to remove the spark plugs when turning the motor by hand. It makes it much easier, especially for valve adjustment

[@2carpros]

Yeah true. Sometimes I get ahead of myself and put plugs in when you didn't need them in yet. Thanks for watching!

[@stevenbruce2659]

Great video series of your build. Good tips I wish I would have known when building my 402.

[@markleedham6114]

Great videos. The only suggestion I would like to add is to use sealer on the intake bolts. I would use a non hardening sealer such as Permatex #2 on the bolt threads

[@tonybustos2396]

Very informative😀

[@2carpros]

Glad it was helpful!

[@artmenchaca4786]

Yes!! Another video.. can’t wait to see the end.. 👍👍

[@2carpros]

Coming up fast. Thanks for watching!

[@hendrikbirke]

🏁🏁🏁 Thank you! This channel is amazing! 🏁🏁🏁

[@2carpros]

Thanks so much for watching!

[@pbettselectric134]

Hi how are your lifters doing. I had to change to a roller. My flat tappers 4 of them failed. Let me know.

[@thelagzone8618]

Also your videos are awesome

[@2carpros]

Thank you so much 😀

[@ekitching]

With all the money you invested in aluminum heads and roller rockers, I would have gone with a roller cam. No break in worries, and more power.

[@2carpros]

Hydraulic Roller or Solid? Thanks for watching!

[@ekitching]

@@2carpros Most guys install hydraulic rollers if it is a street car. There are a few solid rollers, which make more rpm and more power, but there is a tradeoff, they are less reliable and you have to check them every so often. Pay close attention to compression and head flow when choosing a cam. Also, use good roller lifters like Crane or Morel. Gen 6 blocks are better for roller cams because the lifter bores are longer and more accurate to help keep the roller lifter in alignment.

[@nightsnake64]

do you have a part# for the intake gasket set?

[@designsinorbit]

So I've been following your series with my build. I am finally to the heads. I have the roller rockers and cam. It's about the same install as your flat tappet, right?

[@2carpros]

As long as they hydraulic lifters then yes. Thank for watching!

[@donzi9218]

hello, what did you spray the seal with?

[@2carpros]

Spray adhesive. Thanks for watching!

[@bradelliott7279]

Enjoy the videos. Didn't see part 12?

[@2carpros]

Thanks so much for watching Brad! Part 12 went live this past Saturday. :)

[@theshark2804]

454 is already built. But now I want 1 piece pushrods and roller rockers. Can I replace with same spec or do I need to measure everything again

[@2carpros]

Just measure them and make sure you get the same length everything and you will be good to go. Thanks for watching!

[@keithscudder7136]

I've just remembered something, if a Gen 4 454 is re-built with the old iron heads, wouldn't the unleaded gas give them a problem? Thanks in advance Teacher !

[@2carpros]

You might run into valve seat issues on the exhaust side. But if they have been rebuilt in the last 40 years or so it will be fine. Thanks for watching!

[@gwarn4990]

Informative video and thank you for posting. One thing that I feel was missed was what type of sealant or anti seize on the threads ?

[@2carpros]

Thanks so much for watching! Everything I used in the video is in the video description.

[@mikerogerson5951]

what header on the drivers side ?

[@user-nb2gi9bd4w]

Hello what was the part number on the intake manifold gaskets ?

[@loganshotrod4x464]

Is there a way to run a solid flat tappet cam in a 454 & still get oil to the top end? I don’t want the cost of a roller cam & I don’t like hydraulic lifters

[@jamiewoods9222]

great video. Is the exhaust and intake rockers the same ratio and what ration is best for this. I'm building an old 427. the block is from 70's and Dart II or AFR Aluminum heads

[@2carpros]

Yep! I like the stock 1.7 ratio. Thanks for watching!

[@shawnpincksten6065]

There's no link for the spray adhesive

[@jamesreitmeier1974]

Thank you for the videos. I have vortex heads, is there any difference or is the process about the same?

[@2carpros]

Hey that's for watching James! Yeah it is very similar. Just double check the torque sequence and spec.

[@vezina808]

do i need to set the rtv overnight before adding the fluids after installing the intake manifold?

[@2carpros]

Yeah I would. Thanks for watching!

[@dakotacain32]

If I'm building a 496 from a 454 what cam would I use

[@2carpros]

The bootlegger camshaft I used in this would work for you. It depends how much lift and duration and overlap you want. Summit has a great page on it. help.summitracing.com/app/answers/detail/a_id/4698/~/what-camshaft-should-i-buy%3F Thanks for watching and good luck with your build!

[@davidbeutler7665]

So what is it that makes the different length rods. Is it the lobes on the cam, or it being a big block or is it the aluminum heads? Or the roller rockers

[@2carpros]

Yeah if you want to get super technical you can change your pushrod length to adjust for lobe lift or if you have solid lifters or something like that. We didn't change too much so the stock length will be fine. Thanks for watching!

[@madrabbit9007]

There's no time for lubrication. There's always time for lubrication! -Movie: Evolution

[@2carpros]

Always better to have more than less. Thanks for watching!

[@MrLaricus52]

Will those push rods work in a all gen 4 and 5 454 with 4 bolt mains?

[@2carpros]

Yes if you have stock tall lifters. Thanks for watching!

[@thelagzone8618]

Do you have a part number for the rocker arm nuts you used?

[@2carpros]

They came with our rocker arms, link in the description! :)

[@tedslife7086]

I have these heads and I lost my manual after I installed them. How many miles till I adjust the head torque again? I read they need adjustments after break in

[@2carpros]

I didn't read anything like that on mine. You can check Edgebrook's website for it. Thanks for watching!

[@laroseperformance]

Did y’all take out the inner springs for break in or is it not necessary? Thanks

[@2carpros]

Great question. Some people do that and some people will swear by it. We didn't do it here and it worked out great. As my Dad always says "Those differences is what makes racing" So you can if you want to but I don't. Thanks for watching!

[@laroseperformance]

@@2carpros I heard that! I’ll definitely keep watching, very informative videos.

[@kalemkoplin2605]

What does the 1.7 refer to on the rockers ?

[@2carpros]

For every unit of measurement on one side of the rocker it puts out 1.7x distance on the valve. Thanks for watching!

[@enginebuilder2958]

could you use a taller intake like a Victor jr?

[@2carpros]

You could! But then it wouldn't fit under my hood. Thanks for watching!

[@cr500mike]

LIKE !!!!!!!!!!!!

[@Blazer02LS]

Don't think I've ever seen a torque spec for the locks on aftermarket roller rockers.

[@2carpros]

Yeah I have to mention it due to everyone's OBSESSION with torque specs. KZbin is wild with how many people talk about torque specs. Never talk about it in person, everyone talks about it here for some reason. Thanks for watching though! :)

[@Blazer02LS]

Yeah, same issue a friend has in his videos. People always complaining "he's not using a torque wrench" or similar.

[@Patzfan4eva]

2 Question!! If you’re using roller rockers why not roller lifters? Expense or unnecessary? How long do you let the silicon set up on the ends before installing the manifold?

[@2carpros]

Just unnecessary for the street build we are going for. I work as quick as I can, I don't want that silicone setting without the intake on. Thanks for watching David!

[@polarisaddiction9124]

How can I contact you about a big block question?

[@2carpros]

You can email me [e-mail] or send me a message on instagram @ryansgarage408 Thanks for watching!

[@antilaw9911]

Your heads are square port. And your using an oval port intake. Obviously someone made a mistake. Good videos though

[@user-gt2lo3iq9l]

Is this a vortex

[@2carpros]

Nope. That usually refers to later model big blocks this is a 4th gen
