When concerned in the past I've used a pair of solid lifters as a test before assembling which doesn't help your situation.
There was a thread recently about filling lifters before using. I haven't been doing that but may start the practice.

Yesterday I was doing the opposite, bleeding lifters down with a 5/16 bolt in the vise. They were new old lifters where 8 out of 10 would not compress pushing on them by hand. They must have been filled at the factory. Slow to compress, about 1/16 turn on the vise every few minutes. I don't know how I ended up with 10 lifters, I have a few 4s left over from buying 16.
I think I'll practice filling them as long as I'm at it.

Hopefully someone else with more lifter knowledge will add something.

The Isky is indeed smaller, by about .090 (not exact). With .010 shaved off of the heads and stock gaskets, that would results in the pushrods sitting effectively .035 or 1/32" shorter than stock.

You'll get no complaints from me. I seriously appreciate all of the input and information.

I'm okay with your math .090 divided by 2 minus .010. I hope it works out in real life when spending for 12 pushrods, there is an adjustable one for measuring but probably not cost efficient for one time use.
