Called comp and they argue with you.. I was like fk it, handed the phone to drew, ( mr walking big block dictionary) they went back and forth on the phone and comp tech departemtn finally said:
" well our conputer guy that post up everything on the web said those fit" drew was like so a computer nerd that does programming and web design told technacal department that the push rods will fit, but yet non of you have ever even seen a 8100? line got quite and the guy goes... well apparently it sounds that way.

And they didnt refund my money...
Thanx for the info Kerr. I read about this on Dieselplace.com. A few other guys have said the same thing as you. So a guy shared the Trick-flow part numbers for the right push-rods. The ones I listed are very close. One is exactly the same length, the other is .080" longer.
