I recently purchased a new short block 5.0, from Ford Racing, to replace the worn-out engine in my '89 GT. I also purchased AFR 165 heads (pedestal type), an E303 cam and a set of Ford Racing M-6564-A50 1.7 ratio roller rockers.

I am not terribly experienced in the area of engine building to I am calling upon the combined wisdom and experience of the forum to allay or confirm my fears.

My question is this: with the combination of AFR 165 Heads, E303 cam and 1.7 rockers, should I be concerned about valve to piston clearance?

How do I check this?

Thanks for the help.
