New Valve Springs Are These Good?

[DeadLifter]

I'm gettin valve float around 5,500 rpm. not real sure what cam I have I do know it's not stock. I was wondering if these would be a good upgrade with stock heads?
Which would be the best?

well those aren't bad.. but i suggest the comp valve train kit.. i've had very good experience with these and greatly improved the throttle response and strength of the motor..

You have a link or somethin where I can find this?
Thanks

I`d stay away from those conical Crane springs,I`ve heard of more than a few breaking.

Trick Flow has a valve spring kit for stock heads that includes everything,even the valve stem seals.Check out their site.

Use the ones Thumper puts on his heads.

What does Thumper use?

The TrickFlow ones say they're for flat tappet cams.

The Trick Flow springs will work with a roller cam.
