....Alright, now your listening ...... Yep, aluminum heads with 9:71 compression..... I know you'll be 'safe' there. And what Matt said about the 64cc heads. I believe they 'burn better'. But remember with the 64 cc heads you'll need different pistons than with the 76 cc heads...... Also listen to what Matt said r/e 500 HP. In ANY motor the HEADS are the MOST important part in the motor. Well, it's all important but without good heads you'll never make good power... And plan your ENTIRE motor out before you start buying parts..... bill
