e bay cylinder heads

Thanks for all the opinions guys.
I read the thread on Bryce's Airwolf 220's.
These are small block heads.
We are talking about big block heads here.
If Bryce can do the same improvements on big block heads for about the same price point using quality parts, I can sure be a fan of his.
I believe he is using his own castings with narrowed down water jackets(thicker walls), so he can open up the intakes without them becoming water injection heads LOL. The impression I am getting is he is not using Procomp heads
