Thinking about using them on a 351c that will see 6000-6500 rpm's. Are they worth the $100-$150 ?

Are you referring to rocker arm girdles or main stud girdles?Dan Jones

My thinking is yes. Anything to stablize the valve train and reduce deflection over time will reduce wear, binding, inconsistancies and improve performance. Will the perfomance be measurable? Probably not in tenths of seconds off et's, but in consistent et's. But probably measurable in cost to rebuild worn heads (valve guids, valves, rockers, etc) or broken parts.

Yes they are worth it. Valvetrain stability is greatly increased even in a lower rpm motor. Also, on some applications they will gain you a little et if the studs are moving badly now. I had a motor I swapped rovker arms on went form Lunati 1.73 ratio aluminum rockers with no girdle, to Crower 1.73 stainless rockers with a girdle and the car picked up .06 in the 1/8 (around a tenth in the qrtr). I would definatley spend the money and buy one. PS, I run a Jomar girdle on my cleveland and I really like it.

Do they fit under regular or SVO valve covers?

I have the Moroso covers on my motor (they're relatively cheap) and they fit under them.
