5sfe head work?, built for boost. Options

[Kerr1]

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.

If you are building the bottom end you might as well finish it off and build the head. To be honest I don't know how much boost the head can handle. But with the built bottom end you'll be good, but I recommend for you to at least port out the head. How head flows like dookie. And of course regrind cams. To be honest you can probably get away with a built bottom end with regrind cams for the head and a valve job done. You can probably hit maybe 300 horses, but will it be reliable? I don't know.
