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.

The weak point in the 5s head is the cams, they just plain suck. There are several companies that offer regrinds, such as webcams and others.
I am working on a similar project and when I ported my head, I found A LOT of casting flaws that needed to be corrected. So, I would recommend cams, porting, and upgraded valve springs for starters. edit: the webcams 194 grind seems ideal for the 5s, and they now have more aggressive grinds available , too.
