410'

alright guys ive been doing some research and gathering parts and here is what i have so far. la360 block that is 30 over but i will be going to 40 over. untouched x heads, muscle motors street stroker kit. and everything is else is pretty much up in the air. i will be having my x heads sent out for a full porting job and 2.05 vavles. for the cam im figuring one of the hughes retro fit hydraulic rollers aroun .550 lift at 1.5. compression ratio is 9.5:1. im just wondering if .40 over is to much for the la block?? i highly doubt it is. intake will be a ported eddy victor 340 and i alreasy have tti step headers. carb will be a holley 830 4150hp. i think with the roller rockers and hogged out x heads, 4 inch arm, hughes roller cam, and the good headers i should be making around 500hp at the crank?? what are your guys thoughts on the combo? any advice/suggestions/worries? is it worth it to get the 2.05 vlves or should i stick with the 2.02? would a 750hp carb be better? or a fully ported performer rpm intake?
