Yep, and the new trick flow heads work on LA and magnum engines, and you can stroke either. You can make over 400 CI with the 340 block and make plenty of power. Been running my 73 340 for 34 years, been in two ram chargers and two pickups and now in my CJ5, I think it has proven its reliability and I have turned it 8200 rpms with the stock valve springs on the 71 heads. Thankfully I have two spare 340's just in case.

What fun would that be? 😂

I completely agree with you. We got sucked in by the Black Friday deals. Biggest lesson learned, by the best quality parts you can afford for your build or like buying crap from Harbor Freight, you will be buying things twice and might as well spent the money on good stuff. Let alone the fact earlier this year Speedmaster was caught flat out stealing people’s products and copying them.

I bought a set of the Eddy victor BBM heads. I told procomp straight up that I wanted to see what kind of quality they sold and I told them I would either praise them online or tell people how bad their shit really is. The bare castings was pretty nice, of course they should have been, they was a copy of the Edelbrock Mopar heads. The adjustable ockers was absolute garbage. I sent them back and kept the heads. I've seen procomp/speedmaster heads taken apart. No spring seats for the springs on aluminum heads, installed heights was all over the place, valves that just looked rough, springs that looked like cheap junk, retainers and keepers that just looked like trash. Their intakes always have core shift, I've seen their rods that had the cap screw hole threads stripped out straight out of the box. I have bought two sets of valve covers from them and both sets had to have at least two holes enlarged to fire the heads. I didn't know I was getting procomp/speedmaster valve covers from eBay or I wouldn't have bought them. People buy this stuff and brag about it. They are ticking time bombs.

It can be done either way. We will base that decision, on how the layout of the tile works. 90% of the time we will start with the first course resting on the countertop. Regardless it is a caulked joint at that transition. We use a translucent white silicone. But clear silicone is just fine.

I feel your pain with them! We sent the big block heads back to Speedmaster at our own cost, of $350. After the hearing about them flat out stealing other companies technology, I will never buy another product from them!

I will never buy another one of “their” products. After this experience and then them getting caught flat out stealing technology, that recently came out with valve bodies.

To add insult to injury. We sent the heads back to them and it cost us $350 to ship them back. Not a chance I’ll ever buy even a bolt from them again

It actually runs really well. I’m currently running stock rockers with the heads and not the rollers. I’ll be switching them out soon to test them out. I’ll post a video update shortly. Thanks for checking in!

@@agatemaster5706 sweet! Do you have a dragy?? Or accelerometer app in your phone? A back to back performance comparison would be fantastic 👌🏻

@@timosracecars I don’t. I’ve looked into it. Been considering it. It would be a great test

@@agatemaster5706 I downloaded a free one called gps race timer. It works pretty well and free is a great price 👌🏻

Thank you. Appreciate that

I had ordered the small block heads before the big block. The small block was back ordered. Small block had less problems for sure. But I get what your saying. I won’t buy them again. But for the $1000 for the pair of CNC’d heads, it was worth the gamble.

Well thank you for spending your money to answer the question that so many of us wonder. Buying the less expensive heads. Are they worth it? Each of us can make their own decision. Great video👍

They measured 68cc.

I don’t know the flow numbers.

So far not too impressed with their rockers.

I was happy with the CNC job. They seem to run nicely. We will have to see how it feels once we get the car back out. Btw like your videos on your channel!!

@@agatemaster5706 Thank you very much. I appreciate that. 👍

It was a ton of work. But we’ll worth it. Helped that construction season is slow in the winter in MN

Let’s hope so!!

Definitely leaning towards orange! Go Mango/ vitamin C
