I don’t mean to be critical here but you need to reread my earlier post very carefully and take a good look at the photos. You can’t make “an attempt to get close to TDC” to measure piston to valve clearance. A mistake here will cost you a lot. Bent push rods, bent valves, time effort, gaskets, money.
There is no way to shortcut this. You have to use the correct tools to determine true Tdc and be able to accurately get to 10 before and 10 after TDC. Btw, the intake valve is closest to the piston at 10 degrees after TDC. So you have to accurately measure with a dial indicator and degree wheel to sort that out. No other way to do it. This is what is required with a big cam and stock flattop pistons without valve reliefs.
