Unbeatable value

April 19, 2014
I'm running these with 335 pounds of spring pressure with no issues. I've put about 500 miles on them with no funny noises or readjusting . A lot less valvetrain noise with these than I had with roller rockers. The only drawback I've found is that the head size on the poly lock is too big. They require a 5/8 wrench and on my setup, I couldn't get a wrench around the head without hitting the body of the rocker. I used my old poly locks with a 9/16 head and had clearance.
Pros:
  • Good price
  • poly locks included
Yes, I recommend this product.

Yes, these will work fine with flat tappet cam. You will want to check push rod length to make sure it is correct when changing rocker arms

These particular rockers are not self aligning and will not fit the stock Vortec head. Our part numbers 57533519 and 57533521 are self aligning and will work with the Vortec head.

Good Day Folks! I would like to know if these rockers would provide good longivity with valve spring pressure of 330 pound open? I would like to purchase them for my circle track car. What are the maximum spring pressures they were designed for? Thank you

With a spring that has only 330 pounds of force when the valve is open, these rockers should be a nice fit and offer you excellent longevity. These are designed for a stock car/sportsman type engine application and should work well for you. I would feel comfortable using these rockers on a spring as high as 385 pounds of force with the valve open, but would not recommend them for any springs stiffer than that.

If you are going to a 1.5 rocker you should be ok with the stock length pushrods. You may want to mount these rockers and check your length with a pushrod checker (#50542137 or 50542132) to make sure the geometry stays the same.

You can use what ever rocker ratio you want but this may change pushrod length again. Pushrod length will need to be checked with what ever set of rockers you choose.

These performance roller tip rocker arms come with the new balls and poly locks. They do not require the use of guide plates but at the economical price of $17.99 to $18.99 are suggested add on for longer valve train life. These should work for your application
