So if that’s the case and I have the exhaust push rod on the intake side, that would explain the air coming out of the intake. Would that extra .2” be enough to cause the valves to contact the piston? Also, would that cause the engine to not fire up at all?

I don't believe so. If it were me, I would remove the pushrods and do a cylinder leakdown test with them out; that will definitely determine if a valve or valves sustained damage. It's a quick test if you can get ahold of the tool and have an air compressor to pressurize it with.

An important thing to remember, even if using one piece pushrods, is that the engine is not rotated until the lifters have bled down (just don`t want anyone new to the game to think the one piece pushrods are foolproof).

I think the best thing to do is pull the head and have it checked out. Stock cam intake lift is .350". If the lifters pumped up at all while you were cranking it, it would be the same as a .550 lift cam, which would coil bind the stock springs, possibly breaking it. To be safe, come all the way back down and have the head checked. Explain to the tech checking the head what happened so that they will know what they should be looking for.

Sounds like a plan. Thanks for the info.

Damn bikes are so easy to take apart but it can and does get mind numbing putting them back together. I prefer working on Shovels.. The only thing I can build from scratch (machining by others) and wire properly without help from the outside world.

The devil's in the details, for sure.
