Had planed on using Mast 295 Cathedral port heads but with them having trouble getting there castings need to know if All Pro heads are a good set to go with they need to be Cathedral port heads because the intake I used and the engine bay on this build was all ready mocked up and is done . Thanks for any and all Info. The combo is LSX 427 twin76

Allpro has the best LS castings IMO.

Another plus the AllPro heads have is they use the HIP heat treating process

Hot isostatic pressing

Hot isostatic pressing (HIP) is a form of heat treatment that uses high pressure to improve material properties. Castings for critical applications are HIPed to eliminate internal microporosity thereby improving mechanical properties by removing defects
