I am trying to determine how many people here have a 96-98gt (flattop pistons), PI heads, and the comp XE270AH cams, or cams of similar specs (.550 lift, 234/238 duration), and have no problems with valve/piston clearance and have them running on their cars.... please reply if you fall in this category or know someone that falls in this category.. or if you are one of the ones that have problems with this setup... thanks.
