2v pi cams, valve to piston clearance

[taylor8335]

Can someone tell me definitely that there is sufficient valve to piston clearance on a stock 1999 and up 4.6L 2V motor with a 17cc dish piston using Comps XE270AH cams, because Comp Cams can’t? Comp Cams told me that Ford used three different piston manufactures, I think that this uninformed fellow was referring to the three different piston dish measurements of 11cc 92-98 2V, 17cc 99 and up 2V, and 3cc for 4V motors since 93. There is a lot of contradicting info on the web about this set up, can anyone please shed some light on this set up. Thank you.

They will work, you'll need a spot on degree job. People have often problems getting comp stage 2 and 3's to not have any interference but it should work if done properly. Good news is I believe the 99/00 were a little less compression the 01-04's if i'm not mistaken, which would mean a slightly larger dish.
