Edelbrock Performer RPM (7577) and 360 Magnum CI heads

Thanks for the info, just started taking 1999 donor block apart, original owner said approx. 95,000 miles before Durango rusted out on him. Cylinder walls look very good, with great original crosshatch. I calculated, pistons above deck .008. Good to hear yours were at/near deck height. Option 1, top end only: KB107 pistons, Hughes: Airgap intake, big gulp tb and possibly one of their cams, Intake: PIE magnum eq heads w/ 2.02 ex valves.
