Question. I was going to install screw in studs. Are they really needed? The lunati cam I purchased has a lift of .468/.489. Thoughts on if screw in studs are required?

To much lift for a vortec head.. you need to have the spring seat machined...
At that point you might as well add the screw in studs..
and at that point , you might as well step up to the e-tech heads..
as you'll have the edelbrook alum head money in those iron heads..
922.00 a pair.
the vortec iron heads don't require huge lifts to get the power.. as they flow very good at lower lifts..
G.m. got 340hp out of the ramjet with a mild cam..
I think you need to rethink your build or your part choice/combo. if you are on a budget..
I'd want to know where the cracks where on the heads you had.. and if they really matter.. there are 5.7 vortecs running around for 200k with 100k of that with cracks in the head castings..
