Solid rollers with off set push rod hole issue.

Well people after some discussions with the cam grinder and no admittance to any thing being wrong with their cam core , they did agree to grind me another cam at no cost to me. I am happy with that result so I can't complain from that point.
Now I am trying to sort the roller lifters and get centered pushrod lifters and also re-bushing the block.
Hope by doing all this my issue is solved.
If there wasn't so many flat tappet failures I would have put one back in and be done with it.
I'll keep you posted with what progress is happening.
I appreciate every bodies input and thank you once again.
