2 things I can see Beater is that the 153 crank has a smaller mains if I rcall correctly than the 181, so are you going to turn down the mains or linebore the block? As for other heads the 153/181 valve order is E-I-I-E-E-I-I-E, and the SBC is E-I-I-E-E-I-I-E so the head can be adapted but it requirss a special ground cam ,not sure but I think 151p is the opposite.
