I want to change to roller tip rocker arms. I have stock heads with no guide plates and factory push in studs. Do i need self aligning rockers. Heads are from a 1970 350.
Forget about roller tip rockers. You won't be able to tell any difference over stock rockers. Most of the friction is in the fulcrum not the tip. The roller tip just adds weight with little or no benefit. Spend your money on something else.
