c5 head, best flow. if you are gonna turbo, b18b ported.

Ported PR3-3. B20 + NA = love.

Honestly, I would probably use a ported P72. The slight increase in compression over the PR3 is enough to make me want one. Also note that flow differences are so slight that it really won't matter in a street car, in fact I keep hearing that more pro race teams are starting to use P72 heads as compared to PR3's.

P72?PR3? Im not familiar

p72=b18c(gsr)...pr3=b16...i would personally go with the b16 head with clover leaf welds and some P&P work...now thats love!
