Putting a small block 420 into my 95 camaro.
My exhaust ports are square ports.
Factory lt1 stuff is close but its all d-port.
I'm trying to avoid having to custom make these.
If you guys have heard of anything that will bolt up with square ports in a 1 3/4" primary please let me know.

Thanks Mike

 

My hooker supercomp longtubes have non-D-ports. Kinda oval.

 

All of the LT1 primaries I have seen are rectangular ports. Supercomps are damn good headers too.

 

then they arent right. LT1 exhaust ports are D- shape
