ok i have 3500 saved up and i was going to buy afr 185 heads. edelbrock performer rpm intake and cam along with a 75mm throttle body to go along with my 76mm maf. im thinking 30# pound injectors and a crane hi6 ignition. my main question is will the pistons need to reliefs cut into them because after all this i plan on saving up again and buying a new short block anyway so there would be no real point to pull the pistons out and all that if im just going to replace them anyway. if they need to be modified i would rather just wait and buy the short block and do it all at once. i also eventually plan on super/turbo charging. any comments or suggestions are welcom. thanks guys.

What year is the motor in your car?

P Zero

Depends on the cam. Usually the answer is yes you will need to have the pistons flycut. And go for the victor intake rather than the performer, it would be better suited to the heads.

I saw a motor where a guy threw a set of E7's on an 86 block...
That was funny....hmmm...why did Ford put those valve reliefs in there again?
Self clearancing heads...

It really depends, as P Zero said. You'd should check upon assembly -- good advice on head/cam/rocker swaps.

Edit: I forgot to mention, you can have the pistons fly cut in the car...depending on how comfortable you are with it and how far you need to go.

sorry for not specifying. its a 1990 gt with the stock 5.0 in it. p- zero if i remember right the afr 185s are desighned for the 1500-6500 rpm range. the same as the performer intake and cam.
