so pls i need so advices ?

inake will need to be changed, any idea on what intake youre looking at? meaning is this another budget build? the truck intake performs really well i made 440+ using the l92 heads on a stock lq9, the l76 car style intake works well also BUT needs to be ported for maximum performance, with a nice cam to go with it.. i'm closer to 500 now with the FAST intake, for the truck intake i used edelbrock fuel rails ( got a set if interested ) just need to make some brackets to mount them which isnt hard to do, you can use stock injectors ( find some 42lbs'rs ) deffinitely go with a 90mm throttle body. and some decent headers at lease 1 3/4's.
did you have the hollow stems installed and the sodium filled exhast valves? if not i would reccomend getting them, use prc 660 lift srpings also..
on another note 317s arent your best option if youre staying NA, 243s would be, you want the best flowing heads possible the cam and intake if matched properly will make up for any lost torque..
