Just swapped over to Harland Sharp 1.5 ratio rockers and found that on full lift my pushrods touch the intake runner on the head (top part of intake runner). Unfortunately, i did not check to see how much clearance I had before I took off the Indy rocker set up. I would think i need about .030 clearance.

has anyone experienced this with the EZ heads and Harland Sharp rockers?

Any advice on opening the guide area up?

Thanks,

Steve

I ran harland 1.7's on my indy cnc'd ez and the shop opened up the pushrod holes for me.... you can do it yourself though
