98hawk

I already have a set of new comp 918 and titanium retainers. Looking to install a F11 or F13 cam. Should I get better springs or will these work.

Call Futral.

It's their cam, they know the lobes, lift, etc.

They'd be the best to ask.

It'll save you time instead of waiting on here for a response.

Generally, if you're under 0.600" lift with the 918s you're good to go.

Yep, best just to find out. Both the above posts are correct also.

That's funny, they recommneded the Manley's for me w/the same exact cam!

918's are fine but duals will give you that extra peace of mind.
