Piston Q's
 

I'm doing a rebuild over the winter of the bottom end. I have a good crank, rods, block, bearings, etc.

As for pistons I have the stock 86 pistons, (I can have them machined for valve reliefs). But I'd like to get more compression. I am currently at 9.8:1 in this motor. That's with 59cc heads, stock 89 pistons, etc. Does anyone make a domed piston that will work with a big cam/big vavle head? Any thoughts, suggestions?

I know Keith Black makes a domed piston

ross makes a nice custom piston.. just tell em how u want it.
