Trick flow heads: different installed valve height

Look at the specs on the piston ....are they metric rings or 1/6 of an inch.......what bore size....?,,,,,what coating do you want Moly?,,,do you file to fit....order .005 larger ring.

Go to speed pro or total seal piston ring catalog and order to fit pistons?

Post the specs/part number on the pistons and I am sure we can help you.....
