RHS head valve train geometry issue

OK thanks for the replies - so it seems there IS an ssue - and the Indy rockers are the only ones that appear to address the issue.

I guess that means that Indy rockers on an OEM head would be out of spec but possibly less of an issue.....Thats crazy!

I guess I need to ask if anyone has had NO issues?

That might mean it was limited to one casting run?

Maybe Brian from IMM might know?

@ Moper - They're LA-X mate - shaft mounted rockers.

@ Stroker scamp - Sorry my description mislead you - I not an epxert on this stuff - but the Engine builder tried longer and shorter valves and the issue was the distance of the stands from the valves....

@ IQ52 - seems you've hit the same issue -

Are Hughes rockers the same as Indy?

Thanks for the feedback so far -
