hi, i own a stock 98 gtp. i am doing a total overhaul on the car suspension, brakes, interior, engine and appearance update. now my question. i am going genv blower. the blower consist of minor porting and full polish work. LIM like wise including full port and match. northstar TB setup, MAF and so fort. 42.5 injector and bigger fuel rails. i am using 1.9 harland roller rockers and intense push rods. with the stock timing chain and cam, should i use #105 or #130 springs to prevent valve float. my intent is a full dynoed custom tune, so i am going for the max my combination would allow on pump gas. ANY ADVICE WOULD BE APPRECIATED!
