First, I just looked at my heads here and they sure look like a hemi head to me....what is actually the difference in a hemi head or a semi-hemi head anyway??? the chambers are completely round and the spark plug hole is in the center of the valves and close to the center of the chamber. Maybe they are not as deep a chamber as a chrysler hemi head??? </span>

Second,....I am getting ready to build my motor to put in my 67 Z and I am planning on seeing if I can get 600 plus horses out of my heads !!</span>
My turn: With all due respect to you, you're wrong regarding those heads being "hemis" and when that small block hits the dyno, I think you might be a little surprised. Here is something you might want to uh, ponder:
Author? Smokey Yunick and Larry Schreib; 1983
What you're looking at is a classic open chamber, canted valve head. It is sure no hemi.

Believe me Wayne, I am a big fan of Smokeys, ad I realize he did not feel they were worth the effort. I am really not sure what type of horsepower my motor will make...probably not 600..but I have a plan and I am hoping to make them work. Only time will tell.
And as far as the pics You posted...isn't a chrysler hemi a canted valve open chamber head? The pics you posted when looked at quickly look like a 426 hemi head to me...and my heads look hemispherical to me too!!
Maybe we should agree to disagree...!!
