Scorpion marine endurance clearance?
 

Will scorpion marine endurance roller rockers fit under stock 502 mpi gen6 valve covers or is clearance needed?

Look down the page about 10-15 threads

Looks like that was referring to crane golds, the scorpion marine endurance says made to fit under stock gen 6 valve covers with no interference wondering if someone had actually ran them withoit clearance g anything. The corners on these rockers are rounded off.

I had to use a 1/2" spacer with my stock gen 6 valve covers

It maybe more about nut clearance than rocker arm, the poly locks that mercury used with the crane gold ones were a little shorter than the after market ones sold today, I have one set of the mercury poly locks if you need them.
