How much compression can our 5sfe cyl-head handle as far as pistons and decking are concerned? I can't decide on 9:1, 10:1 or higher?

stock is 9.5:1

you can get it a bit higher by milling the head for a few more na HP, but if your wanting to turbo down the road, i would go 9:1 or the stock 9.5:1 at the most.

No turbo at for me...so what would you choose for an option then for comp. ratio? I would like to deck the head like you mentioned (not too much though)...

thanks guys!
