AusTx your combo is even closer to the motor i'm building

Glad someone else is on board with the E'brock Marine heads! I got a set myself, here's my combo (and yes, those heads will make a big difference over the GM 049's). AusTx, are your Speed Pro's domed? The only domed piston I found recommended for the semi-closed chamber E'Brocks are made by SRP (JE). I'm gonna run a set in my 468, they are -23cc small domed, and come out to around 10.1 with a .039" thick head gasket. My block is going to the machine shop tomorrow. here are my hard parts

E'Brock BBC Oval port Marine Heads, Crower valvesprings
E'Brock Air Gap intake
Crane full roller rockers
Comp Magnum pushrods
comp X4 278 cam, 234/244 duration, .564/.575 lift
Holley 870 Street Avenger, 1" Moroso open spacer
SRP forged slugs
Stock 'truck' rods (polished beams, ARP bolts)
Stock crank, ARP studs in bottom end

I was hoping to get at least the 530hp they got with the dual plane, maybe more since I'm running a little more cam, and bigger intake valves.
