I'm thinking about buying a set of AFR Heads...which would you recomend for a mild 351w. I currently run high 12's with a set of modified stock 351 heads. I'm running 9.7comp with a 66cc head. The cam is a Comp Cams 274 extreme energy with about 234 dur and 520 lift ..Just thought I'd see what heads everyone recomends for a good street engine. Thanks..I appreciate any help.
