you might wanna check on your pistons.
-33 cc's for a flat top piston sounds funny to me as the -33 would suggest dish pistons and not flat top.
using that calculator and an average piston to deck clearance of -.005 i came up with a shade under 8-1 compression.
assuming all your information is correct i see no problem running boost on your engine on pump gas.
i would suggest a good dyno tune calibrated to whatever octane you have available to you
