i set up this thread a while ago :https://www.thirdgen.org/forums/exha...hell-need.html

I have D-port exhaust on my heads, round port hooker headers. they seem to be leaking on my first start up. did i use the wrong gaskets? should i have used round port gaskets instead?

 

i called up summit today, they said to get the gasket to match the header flange and not the exhaust port on the head. i was wondering if anyone knew of SCE brand was any good? thats the only one they list in copper oval port.

 

Don't EVER contact Summit or Jegs for tech advice!!!!

Match the gasket to the HEAD, not the header flange.

Use these: http://www.summitracing.com/parts/tfs-30490931

MLS gaskets are far superior to anything else, will never blow out, and can be reused multiple times.

 

they did make a good point though in regards to the gasket, with the D-port, i have an opening at the bottom of the gasket with the header. if i get oval gaskets then that'll cover the whole thing

 

I used header gaskets from autozone for the L98 aluminum corvette heads and they worked like a charm on my Dyno dons headers

 

I run Fel-Pro 1406 on my D port heads

 

my issue is i have D port heads, and oval port headers. i was told by lots of people here that it would work, it would appear as though i got the wrong gasket though. i'm going to try and replace it sometime next week and hopefully i'll have no more noise out of it
