With the 20cc dish, they are a low compression piston.

They will be 8.94 with a 72cc head or 9.2 with a 69cc head.

That based on either a .027 head gasket, stock deck ht or decking .012, with a .040 head gasket.

Might be good for a low boost blower though, with a stock deck and .053 gasket (8.43).

Hypereutectic pistons are very good... IF you never run into detonation or have anything hit the piston.  You also have to be super careful with the ring gaps when setting them up.

For a few bucks more you can buy forged pistons and sleep well at night.  They'll take a hell of a beating and ask for more...
