Default Fast Burn heads exhaust manifold seal or headers?

Will stock '97 Vortec manifolds seal the Fast Burns? Looking at just the gaskets that bottom is kind of close. Or what headers fit Fast Burns and a 97 1/2 ton?

Fastburns have the D shaped ports similar to the GEn 2 LT1/LT4 SBC.

A Hooker 2806 1HKR with their 1-3/4" primaries should fit.

Default headers for fast burn heads

I just purchased a Chevrolet Performance SP 350 385/405. My plans were to put it in my 91 C1500 Silverado.Now I can,t find headers.The heads have .200 raised D shaped exhaust ports.no one has any thing for me. I called them all.has anyone experienced this?
