[Will 1967]

I have looked threads about this over the years and still don't know is there right or wrong answer;
I'm building bone stock 1967 2.0 (ok, it has NOS 2.0S birals and pistons+Solex cams but stock otherwise), only modification for alu case is oil by-pass modification. So no piston squirters and no external oil cooler.
Ollie's, who did that by-pass mod, said that std aluminium oil pump from 2.0 is OK even if they do by-pass mod. But it has said million times that you should use 4-rib (or better) oil pump if by-pass mod is done.

So is 2.0 alu oil pump sufficient with oil by-pass modification or should I try to source SC oil pump?

For hotter engine I'll use at least SC pump, but currently I only have good 3.2 pumps which I don't want to use it as I want to keep original sump plate, and that original 2.0 aluminium oil pump in good condition.
