ok i'm lookin at a set of heads that say there should be no valve piston clearance problems at 220 degree duration at .050 but the cam i am lookin at and want has 224 degree at .050 is there anyway i can keep my same plan and not have valve/piston clearance problems?

 

you gotta notch the pistons, which can be done to the short block in the car.

 

how much does that usually cost?

 

Not to put down this forums in any way, but check out http://www.streetstangs.net I am sure the guys over there can answer your questions. I believe you can run the afr 165's and a b cam without any valve / piston contact.

 

I am still trying to figure out how he knew which heads and cam were being considered.... oh well, glad to see another Glenn with 2 n's

 

Because if you read the forums he has another thread asking about using that cam with a set of afr 165 heads.

 

if you are using the AFR heads w/ the B303 cam you will be fine. according to compcams with stock pistons and the AFR heads aslong as your cam stays at .512 lift and lower you wont have any clearance problems.
