Valve size

I would like to know the valve size on a 504 engine and were they all the same. Also what is the valve size of a 900 377 lp engine. I"m sure one of case guys no the answer. Thanks in advance

Surely one of you can steer me in the right direction

According to the info I have available on the 504 the intakes are 2" dia and exhaust are 1.75" dia.

Same source, no 377 gas data, but closest I could find is 401D intake is 1.731" dia and exhaust is 1.484" dia
