@stevebuchanan posted:Thanks Roland. It looks like they come in a long and short size. The short ones are for valve cover clearance issues. Those above look long to me. I have tall valve covers and I am thinking the tall ones are better in my case. However, these are uncharted waters for me.
I just read that the long poly locks are needed for stud girdles. My engine had those and hence the tall valve covers. Stud girdles help when high RPM's are taking place. I am not continuing with the stud girdles and will set the rev limiter at 5900 or so.
