Just bought it from a friend, im not really a chevy guy but becoming one. Its got a cold air intake, a throttle body spacer, had the hypertech tuning done and has dual 40 series dumped. Wanted to know a good head and cam setup, i plan on getting headers obviously but from there im lost, i just want a set of heads and a nice cam to make it a bit meaner, nothing drastic but something decent. Im guessing this a tbi motor right? Where would I get an aftermarket intake, are tbi intakes the same as carbed?
