Piston at tdc , found true tdc by moving piston down .050 each way. Put indicator on lifter, brought to max lift, went back .100 then to .050 took degree, went to the other side at .050 took degree...added degrees together and diveded by 2 ...

I watched the.steve morris video and did like that

That's the correct way to do it.
Just had a customer have this problem, and he found that the tool he was using in place of the lifter was messsed up. It was one of those tools that has removable end pieces for either a flat tappet, or a roller, and the roller end piece was loose in the tool and rocking.

CamKing what tool do you reccomend (spelling)? Not looking for a professional top dollar tool. Unless they aren't to expensive...

If you can use the lifter, that'll be fine.
We have a tool we sell for $10

Nope.
It's just a 6" long piece of steel turned to either .842" or .875", and it's got a .750" ball bearing pressed into one end, and the other end is flat(for measuring off of).
