I can hear the knocking under load. If I slowly rev the car up to 3,500-4,000 I dont hear the knock. In neutral, reving the car from under the hood I dont hear a knock. I am pulling the valve covers off today.
Can anyone tell me how to tighten adjustable rockers in case that is the problem. Im still not sure what kind of rockers I've got. The heads are '66 289 heads and the guy I bought the car from said the rockers are 1.6 roller tip.....what exactly is roller tip? Is it different from roller rockers?
