Are they on a wayne county block , and are they t/s heads?
Low deck KB block. The thing was just under 500 CI with a 3.85 bryant crank. I do not know what makes a TS head but these have Ti 2.44 IN and 1.88 EX valves.
The engines they were running had heads and blocks that were not compatible with any mopar block. If they bolt on to a KB block, they were not in those PS cars of the period.
That's not to say they didn't come from wayne cty, just that they weren't in the PS cars.
The B1 ts head is a canted valve head. The heads they used on the PS cars were...."bigger"
