Thread: 1.6 rockers on a bbc

    1.6 rockers on a bbc

    I have a question on running 1.6 stainless rockers on the exhaust side on my bbc. Will the rockers just bolt on and clear my 1.6 springs. The reason I ask is that I have 2 valves that just touch the pistons now using 1.8 rockers and I don't think I will lose that much hp by swapping to the lower ratio on just the exhaust. Thanks for any help Swany

    valve to piston clearance

    I would suggest that you take a little time and do a valve to piston clearance check. If you have two touching, you have more very close or touching. It doesn't matter what cam, lifters or pistons you are running. You don't have enough clearance. A little time spent now is a lot less than the time and money you will spend fixing a valve head that went through a piston.

    speaking from experience,
