[Healeys] Very loud clatter tentative explanation

[Greg Wilkinson]

Hi Steve,
Gary at Rocker Arm had mentioned to me that the head would have to be worked
on so the push rods wouldn't rub with the 1:1.6 assembly. This was several
years ago, maybe they have changed the design. Also, have you checked the
exhaust valve-to-block clearance with the new rockers installed?

Yesterday I replaced my rocker assy with a 1.6 high-lifter from Rocker Arm
Specialist in Anderson, CA.
