Default PtV clearance

I have an 89 5.0 with world products heads and gt 40 intake, headers cold air, exhaust. i dont wanna take the heads off to check the PtV clearance.(The valve sizes are 1.94 intake,1.60 exhuast) will the x303 cam from ford racing fit without having clearance issues? is it too much cam for my set up?

X-303 shouldn't be a problem but you sould always check. You can check PtV (valve drop clearance only, not radial) w/out removing the heads . BTW... you may want to check for a better cam alternative than any of the "cheerleader cams".

ALWAYS check piston to valve clearance. No matter what. You should have about .100"
