What are everyones opinions on aluminum vs. steel? Comp vs. Crane vs. Scorpion? How about Harland Sharp?

Which are best for countering valve float issues by way of being more light? Which are more quiet? Which are stronger under high lift conditions. Which suck?

 

I am currently running Comp Cams Pro Magnums. Even though they are physically heavier than aluminum rockers, they are lighter over the valve. Have also ran Crane Gold's, they were a bit quieter than the Pro Magnums.

 

The pro-mags being lighter over the valve. Is this proven or is it Comps claim? I cant see steel being lighter than aluminum.

 

The steel is actually heavier. It is lighter over the valve because of the way it is balanced. The heavy part is the trunion area.

 

Steel parts don't fatigue. I went with the Pro Mags for that reason.

 

Comp stainless here...

 

pro-mags here

 

No issues with my pro-mags here.

 

promags sound kinda like a sewing machine lol

 

Yeah mine do too. Stronger the spring the more the louder.
Are aluminum any more quiet?

 

I have the crowers and I pull the valve covers all the time they are so loud.

But the tip on a styeel rockers is stronger with less wt. steel is the way to go on a small block.

I ran harland sharps too they were heavy, and rubbed the stud on the bottom

 

pro magnum's and they are qiuet compared to the harland sharp's i had before.
