13bre intake manifold to 13brew, porting advice needed
 

i am building a 13brew and the intake (LIM & UIM) will be 13bre. i know this has been done before and did some searching but didn't score.

the bre intake gasket has a lower floor to the FD port by quite a margin.

is there enough meat on the FD floor to match the gasket?

what is the proper way to do the job... this will be a 500+ hp build.

thanks,

Howard
