Does anybody have heads that require a 1205 and an LT1 intake? Is there enough meat to open an LT1 up to a 1205?

 

Actually the LT1 intake ports are pretty much 1205 sized already, opening them up to that size is a no problem at all, dunno about heads that REQUIRE that intake and gasket combo, since the lt1 intake stock won't take that bolt pattern. Lottsa aftermarket heads take the 1205 intake runner size though.

 

I gasketmatched my stock LT1 heads and intake to the fel-pro replacement LT1 gasket (not sure of the part#, but the ports are very comparable to the 1205.
