What kind of gaskets for ported heads? Im curious as to what kind of gaskets you guys use for
ported heads and intake? All I see is stock sized Felpro
gaskets
Won't the gaskets interfere with the flow of the
heads and ported intake?

Re: What kind of gaskets for ported heads? Head gaskets aren't a concern. The main thing to watch is when using LT4 parts. You must get the correct intake gasket. The LT4 race gasket PN is 12367777.

Re: What kind of gaskets for ported heads? For headers, I always used to use 1406 Fel-Pros. They were slightly larger than a stock exhaust port. When doing the exhaust, I'd have the port matched to the gasket opening.
For intake, I always used the GM/Fel-Pro gasket. If you're using these and still getting interference, it sounds like the port has been enlarged too much. I guess you haven't hit a coolant passage yet?
FWIW, I now use Earl's Pressure Master gaskets. They've got removable inserts which came in very handy when I switch from stock heads (d-port) to my larger AFRs(square port).

Re: What kind of gaskets for ported heads? Just wondering if I could trim the header gasket
or is that a stupid idea. Will that cause header
leaks? I just don't understand why there no
larger sized gaskets made. No problem finding
them for mustangs lol

Re: What kind of gaskets for ported heads? The Fel-Pro 1406s are larger than the stock ports. The only thing they wouldn't fit were my AFR race heads(210+) I "guess" you could trim them since they're not sealed on the end or anything. The Earl's fit almost perfect on the square ports of my 210s.
