Cylinder head decision for 318

not with the pistons way down the hole
measure when you get it apart
all 4 corners is better
what heads now?
those suggesting 11/32 are on the right track
are heads cut for 2.02 valves
more than you need and you do noyt really need any more than a 1.5 ex but you have what you have
watch backcutting the intake, margins and valve job, top cutd and cut widths
