NSA 1.6 RR's (questions)
Ok, so I'm thinking about going NSA since I'll be going with a larger cam. Here's my questions.
Where and how much are GMPP Guideplates?
What kind of machine work if any is required for 7/16" instead of 3/8" pushrods are required? And are 7/16" really that much better? Also who makes some good hardened pushrods? Can you still run a stud girdle with the guide plates (I'm almost positive I can just want to make sure before I purchase)
Another thing I've heard about the aluminum RR's is breakage. On a let's say 7000 RPM motor how long do these usually last before they start to crack etc? Or are they reliable?

What kind of machine work if any is required for 7/16" instead of 3/8" None, but ARP bolts and your donepushrods are required? YesAnd are 7/16" really that much better? Yes, how much, not sure, but why risk it Also who makes some good hardened pushrods? Comp, Trick Flow, Crane Can you still run a stud girdle with the guide plates (I'm almost positive I can just want to make sure before I purchase)I dont see why not
Another thing I've heard about the aluminum RR's is breakage. On a let's say 7000 RPM motor how long do these usually last before they start to crack etc? Or are they reliable? ? I run Pro Mags, no worries here

My GMPP's got chewed up from the hardened pushrods since they themselves arent hard enough. I went with Isky Adj. ones, which I personally like since I can better position each rocker onto the valvestems. Everyone is talking Trickflow, but I havent seen nor heard of how good they work.
