Forged piston brand selection

Ok.cool, thanks guys. :)
Engine guy called today and said 0.30" will clean it up nicely. He also said I need new cam and lifters, but to get him some pistons asap and think about what cam i want to run.
I need to find pistons that will suit the 78cc aeroflow heads , so I've come up with the following.
PTS53183 wiseco have ones in 10.7:1 which should do the trick.
IC9953.030 in the icon/Kb forged range which have them at 10.6:1 with 80cc head.

The wiseco uses a 1/16 rings and the Icon piston uses the 5/65 rings? Why the difference?

So far the TRW pistons are either too high or too low on the compression with a 78cc head, so I might just go with one of the above.

This car will see the strip and I'd love to run a roller cam, but funds don't allow it at this stage. The old cam is an unknown item but I did measure a 470" lift with matching springs . What is safe to go with STD rocker gear and old iron heads?
I'm also using a victor 440 manifold and I have an 850 holley on there at present but have an old school 1050 dominator ready to bolt on as well if needed.
I have 28" tyres on rear,new s60 dana with 4.3 ratio, fresh hemi 4 speed by brewers,ram Borg and beck Hd clutch, still got v8 torsion bars and rear springs, comp eng adjustable shocks front and rear.
I will be getting SS springs, 6 cylinder torsion bars and some qa1 shocks next year.

My cuda needs to beat my good mates
1958 ford mainline ute. It does however have a stout 352 hemi that's supercharged, tilt fibreglass front end, auto, 4 link 9 inch. It's heavy but runs low 11's now and should get into high 10"s. Wonder if I'll ha e a chance?:)
