In my search for more exhaust flow in the other thread, I decided to order 1.80" exhaust valves along with 2.19" intake valves today. Valve seats I plan on using are a 1.875" OD. My questions are:

Will a 1.875" ex seat safely fit into F3TE castings?

Running a factory 1996 7.5L cam and pistons, am I going to need to clearance the pistons to fit 2.19" IN and 1.80" EX valves or will there be plenty of piston to valve clearance?

Thanks in advance.
