I wanted to confirm this before I go further--heres the deal.
I need to put Helicoil inserts into my RPM heads. 2 per head , the #2 / #4 holes / rocker shaft stands --the long studs/bolts .
since the threads are pretty far down in the rocker stand...want to be sure on how deep to drill .
so the Helicoil is about .50 deep. Do i need to simply drill the factory hole .50 deep and thats it? Or does the insert need to go deeper in these particular stand holes ??
Checking before I drill !
Im using studs not bolts on these 4 holes
