<VV> Helicoil Size--Oil Pan Bolts

[shortle]

The engine in my 1962 Monza Wagon has 5/16 X 16 for the oil pan (in the case and the bell housing). I was under the impression these are supposed to be 1/4 X 20. Has someone changed ALL the bolt sizes? This car has a 1965 110 HP engine stamped RH. Anyone?
