The C7RA-A head is from a Canadian 46-48, ie: a C59A engine. I have those, they are higher compression than an 81 head. I think that is your answer. Your oil pressure sounds OK to me, Penrite HPR30 is a damn good oil. I think you're good to go.
BTW: Most engines in NZ are Canadian, unless they've been recently imported from the US.
