I see there is a head, 6272292 that is legal for the 71 402/335 and the 73 454/365. Anyone used this casting? Problem is the 402 combo says the chamber volume is 105cc and the 454 combo says it is 110cc. Were they two different heads with the same casting number? Would be nice to have these and two shortblocks.
