Once we get the 1st set of valves done, and we rotate the exhaust valve on the one we just set is hitting the piston...so we back it off(quite a bit) then it turns...
!!EEEE YIKES !!
If you are absolutely sure that the valve is hitting the piston, then the valve timing must surely be incorrect
I'm not saying you did it, maybe the sprocket set was mis machined or mis-marked Hell, maybe the cam grinder got the cam indexed wrong
Sounds like it's time to get serious. If you can't scare up a degree wheel you can PRINT them from online.
And, you can make a couple of checks by referring to your cam card and figuring degrees on your own balancer
First do the "piston stop" routine to be sure the timing marks are accurate, then determin some point on the cam by measuring around the balancer and calculating how many degrees per inch
For example, the website shows that exhaust closes at 21* ATDC. You can EASILY measure that. Same with intake, shows it opens at 29BTC and you can easily measure that. so there are two checkpoints that you should be able to get EASILY within 2-3* and will tell you if the valve timing is seriously AFU or not.
This thing have hi compression pistons? Any chance the pistons are in upside down?
