alrite im planning on a full build for high boost....3sgte rods....custom pistons(9-1)...and high performance bearings and rings....this is what i have for the bottom end. how much boost can i run on a stock head? what are some mods i could do 4 high boost? if i leave the head alone and just replace valves and valve springs w/ titanium would that be good enough or do i need bigger valves and port and polished head? which cams would b better for a turbo setup? Im thinkin 101..ne1 elses opinion greatly appreciated.

You need to just get the regrind cams if you want a higher red line. Valves and valve springs will just help, not add rpms.
