Anyone know what kind of porting this is?

my thaughts exactly......you need to know the range of the portwork before you go slaping on parts. for example, you're not gonna make any power if you bolt ptmids, boysen reeds, and +6 timing to a set of drag cylinders. you have to match your parts to these cylinders.

I'll measure the cylinders next week then, I need to have them bored to .080 over now so its goona be awhile before I get the new pistons, gotta send these ones back.
