I am getting some 346 heads done for my 383 as one of the 906 ones got a crack in it from overheating, didn't advance the timing after installing the cam.

Here are the recent specs:

Engine: 383
Cam: Comp Cams 268H XE (Intake .477 Exhaust .480)
Carburetor: Edelbrock 1809 650 cfm 4 Barrel
Intake: Edelbrock 7186 RPM
Timing Chain: Double Roller Comp Cams
Pistons: Flat Top .30 Sealed Power

My question is what Head Gasket should I use, I have been looking at the PT1 Permatorque from Fel-Pro or the 1009. The one I took out was a silver coated one but of course I didn't look at the number on it and threw it out like an idiot.
