Anyone have any experience with the Yella terras? If I recall Rookie saw them at the PRI show and claim to be pretty decent at a favorable price.

If you ran the adjuster out 2 turns , the ****ers woudnt make it off the dyno. But we ran them 2500 miles in race engines . I forget the amount of cycles , Max Rpm 9600-9800.
and Yes we had those cool ass torque wrenches to adjust them with.

Yes - I'm not going to run them next year as is. Being out of the range worries me so I need to rethink my plan. Certainly need new pushrods and might switch to the steel lifters.

The torque wrench was money well spent. Really made the job easy - putting plugs back in and valve covers on was the biggest pain.....

Put about 75 miles on it this weekend with no issue, Other than a small oil leak. I reused the blue valve cover gaskets but one must be leaking a little.......
