Better head for 565 BBC - Xperts Help Please
I have slowly been honing in on parts for a 565 BBC. I would like the collective knowledge out there to weigh in on the heads. I am down to two: Dart Pro One 345cc and RHS Pro Topline 360cc (both run $2k)
from online databases on flow numbers it looks like the Pro Topline head outflows the dart at all lift points on the intake side, but the Dart flows better exhaust until .600 lift. So that everyone knows the rest of the combo and not just shooting in the dark - - -
13:1 compression on E-85 pump gas
90% street driven 3400# '68 Camaro shooting for 800hp to run 9's with a th400, 4000 stall, 3.50 gear with a 26" tall tire. 300 degree solid roller cam with a 3500-7200 powerband and professional products hurrican intake and 1050 carb.
I thank everyone for the help in the past and once again look forward to your responses.

I'd use the dart head, .. good proven part, good power and
you can have them ported later.
I can offer a cnc ported RFD 24* with 2.35" valve and flows 450cfm
for around $3350 complete. Makes easy 1050 hp on 565-582's
