Hey people
I have a question , I'm putting together a b20b with p30 pistons and skunk2 pro 2 cams, I need to buy a head tho, but I'm not sure if I should buy a c4 head or a b16 or even a b16 with flat top valves, since in my country we don't have e85, will have to run on pump gas and I want the engine to be reliable, since I push it more on mountain roads, whats your opinion? Thank you very much
