440 XE274 Dual springs? - 04/17/15 02:02 AM
Hi guys,
I bought a 440 that was running a 509 cam and I am switching it to a XE274 comp cam. The springs in the heads are Comp PN 924-16 duals. Comp calls for a single spring, PN 911-16. A few questions:
Am I pushing my luck running the dual spring? Obviously I would break in with inners removed.
Should I replace with single spring, and will the fact that the heads were machined for dual springs cause any problems?
Thanks!
Paul
