who runs 13sec to 12.80 in the 1/4

and no one answerd me if i can shave the heads to raise compression with these pistons and if not i guess im going to get kb 10 pistons

In addition to the answer given after you posted this;

If you mill the head enuff to get the ratio you want, the next problem you will have is bolt hole alignment for the intake manifold to the head. You'll move the heads threaded holes doward. You'll then need to mill the intake....alot, to match it back up.
Sometimes milling the heads is a good choice, sometimes not. This would be the "Not" time.

DusterBoy15 so instead of shaving you jsut got pistons?

This would be the best and most cost effective way to get the compresson you want while also not only getting a better piston and piston position, but a lighter piston. Though an added cost of balanceing comes in, the new set up will spin faster and easier making more power.

The mentioned KB 107 piston is good.
The pictured piston is a Fed-Mogaul thats coated. Better in that area for the anti scuffing coat is a plus. I think I seen them in Summitt racing sold with rings for something like $250 or so bucks.

DJVCUDA is right I think. I think you should find a group of MoPar guys and find a machinest that knows MoPars with a good soul to teach you the in's and outs. Someone who doesn't mind you in the shop asking 1.1 bazzillion questions.
If you find such a guy willing to show you, this person is worth a billion dollors and alot of rebuilds that you would have otherwise, wasted money and time on. Make sure you thank him when you find him.
