Thread: Rebuild or Replace? need advice!

Scooter, don't you have a 3" crank you can let him have?

loner, the heads are gonna be the problem. You'll have to spend a wad of money to crutch 'em up with other parts to try and get any power out of the motor. the best part of 'em is the 76 cc chambers. You'll need those with flat-tops to keep c.r. down to a level to use with pump gas.

there's just no way around it, horsepower costs money.

Here's a set of World Products S/R Torquer heads on ebay. Big valves, small 170 cc intake runners for high velocity of the intake charge, 76 cc chambers for a reasonable c.r. With these heads, stock 4-eyebrow pistons, zero deck and a 0.039" gasket, you'd be at 9.26:1

This guy has 99.4% positive feedback, so chances are he's ok to deal with. I'm not saying you should buy these particular heads, I'm just showing you that there are affordable heads out there.
