Hello everyone i am curious what Valve springs you used on the Mopar 312/590 cam i am running a set of 452 heads on a 440..
Here is why i am asking i had comp springs part # 929-16 and the rubbed my Rocker arms. Then i changed them out to a spring that was a little bit less in Outside Diameter of Outer Spring..
Then someone suggested i try the Crane springs 99838 but they are out of stock.
Comp has a valve spring close to that part # 994-16.
I just want to make sure that it is a spring that will meet the Requirements for safe operation and fit.
the spring will have to be a narrower ( Outside Diameter of Outer Spring.. ) to not rub than the comp 929-16 or 928-16
Somewhere in the 1.465 area.
Oh yes i am using the Mancini 1.5 Rockers arms kit.
Any help would be very Appreciated.
