Okay, I bought 2 of these cheap kits and just got back from the machine shop.

Long story short: Be sure to measure everything before you stick it together.

Details; Pistons all mic'ed good and consistent.

1 ring was past .016, the other 3 were tight at .007 or .008.

The cylinders: 2 were a bit tight, but could probably be run with extra caution during break-in. 1 was too tight to run and 1 was too loose.

So, I think I can put the bike together using select pieces from the 2 kits.  As for the leftovers: The 1 tight cylinder can be honed of course, but 1 cylinder and 1 ring are too far on the large side and so are not usable.

Bought a third set for $76.00 and got a $40.00 refund on the 2nd set, so I paid $96.00, $37.85 and $76.00, $209.85 plus tax for 3 top ends. I haven't dial bored any of them yet, just put them on the shelf for now. I did notice the external portion of the casting above the T2 ports will need to be built up with weld for serious porting. Mark, the drop of several mm below BDC in the liner at T2 won't be a problem, in the 70"s we would intentionally lower it under the impression it helped torque, oh well, times change.

nice. yeah i didnt think THAT itself was the issue, but the ones that are sold w that tend to be different (over all) than the other ones sold for a bit more, was just an 'identifier'' is all.
