as you can see in my sig, i have aftermarket heads and a cam. im still running the stock rocker arms, and while im sure they wont free up a lot of horsepower, i was wondering if they would be a little stronger and less prone to breakage. can someone please give me the pros and cons to aftermarket roller rockers and some different brand/style options?

you can send the stockers off to harland to get them converted from needle bearing to roller, think its like $200.

I don't like stock rockers in aftermarket setups. They have a wide wipe and will accelerate valve guide wear with increased spring pressures. I have personally used the Cranes and the Yella Terra's. Both are very good quality rocker setups. The Cranes use a shorter pushrod and are also available with 3/8" pushrods if you have a stout system, which minimizes pushrod flex. Whatever you use, make sure you spend the time to set up the wipe and the pushrod length, don't just bolt them in.
