Help me decide on the induction side of my FI build. Holley+PRC LS3 or Edelbrock+AFR? I am building a 364 cu in boost build with K1 rods, Diamond pistons, and a stock crank. It going in a 70 nova so hood clearance is not an issue. It will have a GT4788 turbo on it and I am using the stainless headers off an OFI kit I bought on here. I bought a sheetmetal intake awhile back off a member here that was built by Hardcore for their 7 second ride back then and I thought about using it but I really don't know how the ports are going to match up if I go with LS3 port style heads on this motor. So, now I think I am going to go a different direction with the intake and heads.
I am looking to go either with an Edelbrock Pro Flo XT intake or the Holley Modular style intake with the EFI top on it. The only thing is that the Edelbrock only comes cathedral port so I am stuck using a cathredral head on that intake which is leaning me toward an AFR head for the boost I will be running. If I go with the Holley, it only comes L92/LS3 port. I am going to use an aftermarket casting no matter what so I would have to use the new PRC LS3 head or a MAST motorsports LS3 head. The question is which head/intake combo would you choose.
Here are some pics of the Hardcore/W2W intake.

I know LSA heads fit on an LQ4 so does every other head except an LS7 head. I am just trying to decide whether to go AFR with the cathedral port or PRC or MAST aftermarket LS3 casting and which intake to use with them.
I am not wanting to use a factory casting since it is a 4 bolt setup and I plan on running up the boost to 22-25 psi every once in awhile.
