Re: Some "Dynomite" Heads!
Here are the heads assembled and ready to go.
Machine shop decked them to get the chambers down to 39cc. I cc'd a couple of chambers after the fact to compare. My numbers came in just slightly higher but still less than 40cc - must be some difference in technique.

Re: Some "Dynomite" Heads!
Nice collage Cliff, didn't know you were so artistic lol
I'm thinking it should be in the 430rwhp ballpark. It's mostly proven technique - with a little extra degree of precision. I also checked the valve stem length using my pipe method which allows comparison to stock values. The machine shop trimmed them up some but they are slightly taller than stock by about .010 - .015in. This should be fine and get soaked up by the hydraulic lifters from what I understand.
