Correct. I think they called it Bon Ammi back then, and it was a mild abrasive cleaner used to clean the scum from you bath tub. LOL. They also had a problem with rocker studs pulling out at higher rpms, and since the first 265s had flat top pistons the valves dinged them pretty bad. They found out that a gauge at the head assembly wasn't adjusted right and the studs were not installed to the right spec.
