Yep. It is called "Core Shift". Caused by a deviation during the casting process due setting on the mold, mold alignment issues, mold temperatures and pressure differentials. One of the many reasons why the fast guys spend lots of money testing and going through many castings.

I knew a local machine shop that had a back room full of castings. He let me take several for testing. My ‘56 was newly allowed the “520” castings. I discovered the 520X castings.
Held more CCs than legal. I had decked my block a lot, so needed to mill the intake side of my heads a lot so the manifold would fit. Got rid of some intake CCs.

Andy, here's the thing....just because you can spend a lot of money, that doesn't mean you have to. Or that you should. Each racer should race the way they want to race, period.

And if that means you're not the killer azz kicker in your class, so be it. You can be a player by watching the qualifying sheets and being careful. And if you get a heads-up at some point...hey, the fast guy still has to run the race and turn on the win light first. Lots of things can, and do, happen.

Don't let not wanting to spend a fortune deter you from getting into Stock or Super Stock. It's a lot of fun, believe me! :) -Al

Completely agree Alan, I don't think someone has to be the fastest or 'coolest' or have the best paint or bazillion $$ tow rig to have a blast racing. There is a lot more to it than that for me.

I am determined to build a 14-15 Camaro to run SS/FA or SS/GA. I would like to run pts meets, GLSSSA or similar races, No-Box stuff and 1/4 mile racket races too. I plan to do as much of the work myself as possible. I can TIG weld, fabricate, CAD design, do FEA and CNC machine too. I will learn CFD as well so I can design, machine and flow my own heads and intakes. I want to build my own motor and trans as well. I will paint the car, if I have to. Never done it, but I am willing to learn and try. I want to be able to say this is MY race car, I paid for it, I designed it, I built it, I drive it and I am very proud of it. (good or bad)
We'll see if put my nickels were my mouth is....

I can't wait to get back to the track, I hope everyone is staying safe, and sane through all of this.

Re: Stock Eliminator Cylinder Heads

I have a completely different result going through castings and flowing them...
my brother and I went through dozens and dozens of 882's and 450's for our cars...
you could have threw them all in a pile closed your eyes and grabbed a pair and they would have been as good as any other dozens of heads in that pile...maybe every 882 and 450 just suck...
that being said though I still try to pick a set that look like they have the least shift and least flaws.... not for performance but for reliability...

Re: Stock Eliminator Cylinder Heads

Sounds like a path well thought Andy..
