Lt4 Intake Gaskets...which Ones?? Please Help

ANYONE HAVE THE GM PART # FOR LT4 INTAKE GSKTS??

I know these two numbers:

12528884
12367777

People say one is good to use for porting and the other is not?

Thanks

Part number 12367777 is the one you want to use. I just used them on my 396 build up with AFR LT4 210 race ready heads. This is the "HP" part number. The other part number you listed is for a stock LT4 intake and head setup, which you dont want to use for porting.
