Default 1mm oversize inlet valves
if i got these fitted to my head 1999 on a 96 block would there be any interference issues between piston and valve?or do i need to increase the valve cutouts on the pistons?

You won't have a problem with the pistons if installed correctly.

Check piston to valve clearance. Is the head already on the shortblock?
