head opinions

[GT_green_GT]

In your alls opinion what do you think these will give me? Edelbrock Performer 5.0 Aluminum heads. 170cc Intake runners, 60cc combustion chambers, 1.90 intake 1.60 exhaust valves. Springs rated to .575" lift hydraulic. Pedestal style rocker mounts. right now all i have is longtubes and gears. Should i port and polish em before i put em on if i do get em. they are used.

port/polishing will help. they are pretty decent heads. i would find an intake to though while your at it, that will be the next major bottle neck.
