Anyone using HS rockers on Indy EZ heads - 05/10/11 12:31 AM
Just wondering how well they mate up to the valve tip.

Checked mine out on the geometry, looked like everything was in order....

They typically fit very well on STD EZ's, and SR's, Need different for big EZ. Otherwise they are a good rocker for the EZ family.

My machinist added lash caps to get a better sweep of the roller tip. Here is the first picture. These are 1.5 ratio Harland Sharps.

Stanton- The Harland Sharps fit very well on the EZ's as far as alignment with the valve stem. I have the CnC'd 295's. However, I did have to have the pushrod holes in the head opened up to clear the pushrod (1.5 ratio) with a .620 lift cam and 3/8 pushrod. I think I would have been okay had I went with offset Intake rockers. The pushrods rubbed the intake runner. They did not bind but definately made solid contact with the runner. When I had the holes opened up the porosity in the casting allowed oil to seep through the intake runner. I ended up using silicon to embed the aluminum and have not had any problems. Food for thought! I was very impressed with the HS rockers!
