Default I want to raise my compression

How can I raise my compression from 11:1 to about 13:1? I'm on a limited budget so can't spend too much but I will be pulling the motor out so I figure I might as well do everything while it is out. I also think I will switch over to a solid roller.

Thinner head gaskets and milled Heads.Of coarse you might have problems with the intake lining up after.
Might be cheaper going with high compression pistons.

Pistons would do it easy. You'll need to make sure the domes wont smack the valves, too. Watch the clearances. I guess you've already bid your farewell to pump gas.

yeah, no more pump gas. I never drive it on the street anyway. I guess I could just swap out pistons. Either way, I'll have to get pistons with reliefs, or put them in myself.

You can run as high as 12.25 with a big cam that bleeds off compression. Just all depends on the setup. The higher compression the bigger the cam. PM me if you need some help. 13.0:1 aint gonna happen on pump gas

You could also weld up the combustion chambers, then you wouldn't need to buy and install pistons, plus the P to V clearance wouldn't suffer. That should save you money as well.
