Yeah, I do like that about the LS motors, Chevy dropped that shared port thing.
Unfortunately, all that is available for the 4.3 are just factory Vortec heads. I forgot the flow rate, but it boils down to a max of about 50hp per cylinder with stock heads N/A. Not too bad, but that exhaust is definitely a restriction. I just look at the glass half full and say it saves my transmission some heart ache
FWIW my cam is just large enough (212 duration at 450 lift) to give me optimal air flow without being a burden on excessive lift. I should be able to hit a good 7k RPM and still make power.
