Define a ton?
A new set of Crane golds are right at $300
Comp pro mag $270 range
I have heard decent things about harland sharp but have never used them and don't know if they have S/A rockers but they are a good bit cheaper. I have also got a couple of great deals in the parts section of the forum in the past.

The LT4 springs are made to use with 1.6 RR. They are very reasonable compared to aftermarket springs. I think I paid about $36 for a set, new. They work with the LT1 retainers or you can get the LT4 ones. Don't scrimp on the rockers and don't let anyone talk you into Proforms, they are complete junk.

I doubt that anyone would want to run a cam that big on the street but just thought that I would share some info. I am planning on buying some Comp pro mags myself for my 91.

I've been running the GMPP 1.6 RR for over 50K miles on my daily driver LT1 (the GMPP RR are made by Crane, almost exactly the same as the Crane Golds). They are fine, esp with a stock cam.
I agree about upgrading your springs, the LT4 springs are great with the stock cam.

For a street engine running modest spring diameter and pressures, the Crane golds are fine.
But why you step up to big springs, like 1.625s, and/or high pressure to accomodate radical cams, the Cranes have a problem.
First, often the under side of the rockers won't clear the larger diameter springs and need to be ground for the necessary clearance. This isn't really a biggie, but there it is anyway.
Second, the Golds are aluminum and are not as rigid as Pro Magnums so they flex more and this effect lift and duration on the running engine. You'd want the most rigid parts in your valve train; those that don't flex. That's why we move to .080 wall one-piece seamless, blah, blah, blah pushrods, 7/16ths studs or a shaft rocker setup, etc.
Third, the Golds are a pretty old design and I don't believe they have the latest technology incorporated in their design.
Just my thoughts.
