There must be hundreds or maybe thousands of guys that have 350 blocks and double hump heads taking up space in their garage, so this should be of interest to a few of them.

Brzezinski has said on their cylinder head site that of all the double hump 2.02"/1.60" heads they have flowed, they average the following flow figures, so I feel confident in using them on a DynoSim pull.
.100 64 57
.200 128 107
.300 173 125
.400 195 141
.500 202 141
.600 202 141

350 SBC, double hump heads, 2.02"/1.60", 11.0:1 static compression ratio, single plane intake, 750 carb, 1 5/8" long tube headers.

Swapped to dual-plane, high-rise intake such as Edelbrock Performer RPM #7101, Edelbrock Performer RPM Air Gap #7501, Weiand Stealth #8016, Holley #300-36 or GM iron intake #14096011. These intakes are basically knock-offs of the Chevy 302 Z28 intake manifold of the late 60's. No other changes were made....

No, he was showing you the difference between a single plane intake and a dual plane comparison to power. Is this going to be a street vehicle? with 11:1 pistons you`ll be forced to use race fuel.

well for one the pistons i have already are forged i got a deal going now on a crank and a set of rods for a pretty cheap price so i would say they go together pretty well the heads right now would be my only set back but still not out of my budget since i already have the other stuff on hand....like i say though im asking for help on this and not tryin to be a know it all because im by no means that...im looking for suggestions and i do appreciate any and all help on gettin the most bang out of it with out stroking or a bottle but that being said i might consider a bottle as well just havent put it in the plans as yet!!

unless its restricted to track only driving with race fuel I would step the compression down. Having to pay $6 a gallon for gas to drive on the stret is a PITA and so is finding it in many locations.

TO be honest if you don't already have the cam, you can make a better street showing and stay on pump gas with a few tricks. I'll post more tomorrow, I need to get to some stuff for now.

BTW thanks for the compliment, its a question I don't think I'll ever be able to answer...
