@Steel1 Has the best way to be sure in mind. Use modeling clay on a piston with a mock up assembly and hand turning to make sure there is enough clearance. "Should fit" is not good enough if you need the notches in the pistons modified for valve clearance.
The pistons have 'eye brows', there are 2 notches on the top of the pistons that look like eye brows or quarter moons.
As suggested, a mockup with clay will tell the tail.
I take it you have not taken the heads off yet.
