Default Harland Sharp or Yella Terra?

Or stock rockers? I searched for them, read about them, didn't see any comparisons. Advantages, disadvantages, pros, cons, etc... TIA

I have heard of a lot of people losing power and having problems when going from stock to aftermarket rockers...

Ive run the YTs on my car for almost an year now and no problems. If your running a cam close to .600 lift then upgrade to a better spring. I have Comp 978s with my X1 cam and made 413rwhp in an auto.

The Harland Sharps are heavy and with that weight over the valve if you don't have strong springs you may float.

Check NASTY PERF. for rebuilt/upgraded stock rockers with c-clips and new trunions. No more spilled bearings and a true fit.

Yeah... I heard of GAINS with aftermarket rockers as a result of less friction. Not to mention the added reliability.

I hope you all understand that there is fitment issues with all aftermarket rockers. Just depends which year you put them on and which head you have.

I like the HS Stock modded rockers personally. Excellent idea, weight, and absolutely ZERO fitment issues.

Ditto, I picked up ~5. I running them with Manley springs and I'm a tad quieter than stock.
