K-B. Top piston gap Question? No guessing. Boar 4.400x.0065=.028 we know this. Full size Bronco 60’s front rear stick running sand tires and I drive it as a daily from time to time.
Problem living…. in Oregon gas is. 91% shit. I want to gap top ring at .026 thou. I also have stock heads that have been well worked over was said to be as good as CJ,s I question that. Low compression heads.
Should I do this it is a 6500 Rpm motor, and that’s only after 6pack?

I am running KB Pistons the guy that did my machine work on my block and rotating assy. told me to make sure and follow the KB instruction sheet or take a chance and loosing a ring lad but if the rings called for a larger gap use it but no smaller gap than what KB calls for.

Ok thanks I liked your answer. so to my next question do I set the ring gap for truck and towing or leave it street?
