Here is a good question. Are the waterpump gaskets the same left and right?one side has three holes and the other side has four. I usually trim the gasket for the side side with the three holes.Only owned one car with the true original waterpump never removed and didnt looked at it . Anyone have a car with the waterpump never removed?

I just removed a original water pump never removed from a 69 nova 307 and it had the 2 hole gaskets on both sides
-
FWIW - I don’t know if 69 is different from 1970 BUT- I have a unmolested 6,000 mile 1970 Z28 LT1 motor , that has never been apart ( except for taking valve covers off ) , and it has a 4 hole gasket on passenger side and the 3 hole gasket on drivers side. I had old NOS GM gasket kit before and it had 1- 4 hole gasket and 1 -3 hole gasket.
I was under the impression that the 4 hole gskts were generic type that were supplied by rebuilders?
I’ve been trimming the extra hole off for years in all our restorations.
Maybe James or Kurt will comment?
Hope this helps.

I have bought a few NOS water pumps - 608s, 609s and they had black 2 (bolt) hole gaskets.

I have been trimming them for years also . Just trying to figure out what is true assembly line . thanks everyone

Two hole gaskets were factory installed so cutting off the extended gasket hole is the correct way to go.
