Not since you changed the head gasket thickness, now the stock pushrods are too long. Better to use adjustables anyway so that lifter preload is set correctly.

OK to use for what? Personally, and there were doubters, I used my stock push rods when I installed my 95" cylinders and pistons. I didn't want to worry about dialing in the correct number of turns with adjustables (plus the added cost). Trust me, everyone warned me about it, especially because I used 'used' cams and cylinders. Well, almost 10k later, and I have not an issue, knock on wood. So, not being an expert, and only going off my own personal experience, I say it should be fine. Now, if I were to later go back in and change cams (which I have NO intension of doing), I would buy a new set of adjustable pushrods, to avoid taking off the top end.... but, I took a risk, and I am fine with my decision...

Heck, I'm not sure what thickness I actually used. If memory serves, it was .030". What does the stock run?

You may be ok. I would mock it up and if you can turn the pushrods between your fingers after the lifters bleed off you will be ok. If the lifters bleed down and the pushrods don't turn with some effort, then thicker head gaskets or adjustable pushrods are options. You should mock it up to check valve to piston clearance anyway.

if the base circle on the 211's is the same as stock you can use stock pushrods with the .030 headgasket. Stock head gasket is .050 or there abouts so you are at -.020. your stock lifters have plenty of travel for that difference. stock lifter travel is .2 and most set the adjustables some where in the middle of the lifter travel. you can safely use stock pushrods with total reduced stack height of .050 or so. I use .030 hg and shaved my heads .038 and no issues with stock pr with cams that have stock base circle.

I should have my 06 Ultra 95 BB done this afternoon, (waiting on the Baisley spring) I went with SS510G's and a cometic 0.030 with stock push rods, after the lifters were bled down the rods spun with my fingers very easy. I'm hoping i'm good also.
