So guys, I'm sitting here staring at my set of GMPP Cylinder Heads that I got from Scoggin Dickey. They have Hollow intakes and Solid exhaust. I'm paring them with a .567, .564 Cam Motion Cam, and then a set of Custom ground Scorpion 1:8's. Yes I'm changing springs. But these valves are also different lengths. With my 1:8's is it necessary to change Pushrod lengths or what? Or if I put it together will it rattle?

I had the same scenario, no probs, just used the T&D adjustable rocker gear.
