Remflex gaskets 12-001 vs 12-004
 

Remflex 12-001: Features standard oval end ports and D-shaped center ports (typically matching standard factory/OE heads and manifolds).Remflex 12-004: Features larger, D-shaped center ports explicitly designed to accommodate aftermarket headers and high-performance cylinder heads with larger port openings.

Just wondering if i put the wrong gaskets on.............i have the 12-001

I have dougs headers and kre 295cfm heads, oh boy

Any of you guys using these 12-001 on kre heads.

The 63SD 980 heads have a wider center hole to hole than ALL other Dport heads.Might have the gasket for them.Tom

Tom S, sorry for the confusion, are you saying the 12-001 would be ok for my kre heads.

I can tell you the Remflex 2" for round ports do not have the right bolt spacing for the center two ports.

I have Remflex on my High Ports with no issues.

001 looks like the correct for standard D port heads.Tom
