Having a problem with the poly lock binding in the back of the rocker when pushrod length adjusted for correct pattern on valve tip. Should I try different rockers?

Check the pattern with a shorter pushrod.

Doing more with less, or something like that.

No, it was hitting at the bottom of the poly lock close to the fulcrum. I found out that a couple of companies, TFS and Harland Sharp make rocker arms specific for the twisted wedge heads. I bought the Harland Sharp ones and the intake and exhaust rockers are different. This corrected the problem but I had to buy another set of pushrods that were even shorter, 6.900" to get the correct contact area on the valve tip. All looks good now. EXPENSIVE LESSON! Thanks for the help everyone.

damn I hope I don't run into the same problem, I have a set of crower SS rocker arms sitting my garage that will be going on my 11r's.

Thanks for the update.

Well I learned that there are rocker arms that are made specifically for twisted wedge heads. I ended up with a new set of Harland Sharp arms. They use different rockers on the intake and exhaust valves. I had to get an even shorter set of pushrods but now my contact is centered on the valve tip and there is no clearance problems with the poly locks. Everything looks good and runs good now.
