I'm using gold springs and have a cam that will have .628 on the intake and .632 on the exhaust side with Morel lifters.

I know the gold springs are rated at .650 lift. I'm concerned about the life expectancy.

Thanks for your input.

No kidding? I have a set of those sitting on my floor. I got them for more seat pressure as my cam is going to like to rev. I didn't know their lift was rated so high.

I see no reason why they shouldn't work. With a cam with that much lift you are going to be changing springs every so often no matter what.

No kidding, they came with my PRC 2.5/5.3L heads. They look good don't they?

I think they are a bit overkill with my XE-R .581 lifts, we will see how the do.
