Yesterday I got to see a set of KATECH BGE CNC heads put a 25hp beating on a set of MMX ported CNC heads on a 431ci BGE block build , both test were using Comp cams Stage 3 HRT 228/236 , Edelbrock Intake dyno headers (1 7/8) 90mm TB Holleys Terminator EFI set up......FWIW the MMX were 10 hp better then Frankenstein Apache heads.
