I have a few rocker nuts that keep coming loose (intakes 5,6,and 7) so I'm wondering if it would hurt my engine to put lock nuts on the rocker studs to keep this from happening. I just have a gut feeling that this wouldn't be good for the engine. By the way, it's a 350 with holley systemax II heads.
While I'm posting, I might as well make it worth while --
I'm replacing my radiator -- I'm probably going to get the Griffin aluminum radiator, but I was also looking at the GM aluminum radiator -- is there major difference between cooling performance between these two?
Also, I'm thinking about switching to roller lifters, cam, and rockers, so what would be the best combination (ratios, sizes, etc.) of rollers to buy with a stock 350 block, holley systemax II heads, victor jr intake, edelbrock 650 (which will probably be going to fuel injection in the near future), and MSD ignition. Thanks for any help in advance.
