414 Stroker Combination Engine HP estimate

But he didn’t say they were cnc’d heads. Here’s Indy’s heads in different versions but I wouldn’t put a lot of faith in Indy’s flow numbers. Hopefully that will change with the new owners. If you take your heads to Joe blow down the street fully ported may mean he hit them with a sanding roll.

You got that right !!!! ....

I found out yesterday that the heads I have, which had been ported and hand blended barely flow 239 cfm (intake) @ .600, and 181 cfm (exhaust).

These are the famous Procomp heads ( that btw explode ).........

I will place a new Thread on this subject.
