If you building a tru Blown alky motor your not considering Indy stuff (not bashing Indy just just another level of performance). Typically the intake and heads come from the same mfg, for instance I use Veney Heads and intake. If you have Brad heads you use a Brad intake and so on. Your not going to get much better than Stage V. How about a list of what parts your using? Everything is bigger on a blown alky motor 7/16th push rods for instance, The Rods are beefier, Piston pins 1.09"... The Blown alcohol Hemi is kinda like a SB Chevy. There are a lot of parts mfgs and sellers out there.
