RE: AFR 185
that'll depend largely in part on the cam you will be running.. but if it is a cam with a great deal of lift and duration and installed straight up ..you most likely have to notch him

RE: AFR 185
Lift is not an issue for piston to valve clearance.
As stated though, it depends on the camshaft opening and closing events at particular points. More precise, the intake opening and exhaust closing (aka: period of overlap).

NO SHYT SHIRLOCK.... THAT's not the point I was trying to make even though the wording sounds as such

RE: AFR 185
No problem I'm not mad......I know that lift is not a determining factor of ptv.. more so I was trying to emphasize that I have seen afr 185's on a stock bottom end and cam work without notching but once performance cams enter into the picture without knowing all the specs at what degree in the cycle the valves are timed to open.....more so I should of said in my first post...performance cam + 2.02 valved head = clay the pistons and check for interference which often occurs on the corners of the valve reliefs... or we could just avoid the whole issue and use a canted valved head like a twisted wedge head.....anyway sorry for being so defensive 5spd gt

RE: AFR 185
you most likely will be fine.. but either way it's always a good idea to clay the piston and check your clearance.....look at it this way....would you want to ruin a expensive set of heads from the get go??
