If I have a stock bottom end and the usual boltons with cam (.499/.510) and intake
will I have to notch the pistons on my 1990 5.0 gt if I get the 185's since they have 2.02 valves. Another ? my dyno is 271hp/301tq at the wheels, then after this installation with the heads what cluth is best for my car( also 3.55 gears).

Thanks
