Now, everyone knows I'm a hemi guy, but this is interesting. Everyone knows that the old Poly 318 was a semi hemi, similar to a big block Chevy.
BREAKING NEWS-SMALL BLOCK HEADS BREAKTHROUGH may make all wedge heads obsolete! Left is a Poly "A" block with 360hp heads and Edelbrock Performer... Right is the 360hp block they came off of with Poly heads installed and Hot Heads manifold we're using as the pattern for our new Poly SS-X and SS-2X manifolds... Poly heads properly prepared will really "wake up" any small block no matter whose heads you already have! The Poly combustion chamber and Hemi-like valve layout are far superior to any wedge design! Aluminum poly heads for small blocks are in the works...Hot Heads, who does a lot of early Hemi stuff, is involved in this deal....
