what heads are you using? from what i researched roughly milling the 317 heads with stock .051 gasket should bring you around 10.2:1 i believe.You shouldnt run into ptv problems with the dished lq4 pistons and stock valvetrain.

you can run 243 heads milled and still be clear of ptv with a mild cam under 600 lift with stock gasket.thats what im upgrading to next month and comp should be around 10.8:1 for a decent bump in power.

reach out to some vendors and discuss cam choices based on the plans for your heads for a package that will perform.
