Flat tappet to solid roller...

Yes the pushrod job looks very pretty, BUT, I'm sorry, I'm going to be the nay sayer here. Do not run the engine any more with the spliced pushrods. You are courting disaster there. There is a reason that pushrods have the cup end installed in as far as they do and not pushed in just 8mm or so.
He did say he was waiting in new ones and these are just for engine break in.
