I'm ordering a set of the LPP headers and was wondering which header gaskets you guys are using? I've been reading people using the Fel Pro ones or the Percy's ones. I have yet to see a good picture of the ports on the LPP headers for LT1's, but I know all the gaskets are Square shaped. Will that matter if the LPP headers have a circular shape port?

 

Felpro 1406s on mine.

 

Felpro here too, they were the only ones I could get to seal.

 

lpps come with header gaskets and the they look like good quality.

 

I know they do but most headers seem to include the worst sealing gaskets on the planet so I wanted to avoid any leaks down the road right away. So it seems the Felpro 1406 over the Percy's?

 

I just used the LPP gaskets and they work fine. No leaks.

 

LPP gaskets and clamps are garbage. I used Remflex gaskets and Stage 8 locking bolts. You can get the gaskets from poweraddersolutions. Talk to Chris. He is a sponsor on here....

 

Go with the FEL 1406 and don't look back.
