The reason I'm thinking GT-40 heads is the 64cc chamber---this will effectively bring my compression ratio down to 10.5:1 with these TRW "12.5:1" pistons which should yield a "pump gas" fuel requirement.

Slick: $900 for new pistons? Another reason to not go BB FE... By the way, you still owe me a ride in that thing.

Blykins: I was going to call Ford Racing Tech Support to see if I can get actual flow numbers for the "Y" and "X" GT-40 heads.

Anybody try those Comp Cams "beehive" valve springs? I'm curious...
