thanks guys. as far as i know ill need to deck the block and also mill the heads to get the cr up a bit. i heard a lot of good things bout the 302 castings, but i just cant afford the bigger valves and am not too experienced with a die grinder, so i think for now ill jus mill some 360 heads down and run em for the time being. maybe later ill upgrade to a set of ported 302s with bigger valves
