Injector Housing Gaskets for stock engine
 

I am replacing stock unported injector housings onto stock unported heads. The injector housing gaskets that I have in stock are the same size primary and secondary, approx 37mm. However, the primary ports in the injector housings and heads are smaller, approx 32.5mm.
On the secondaries, there is no problem - it is just the primaries where there is this gasket mismatch.

Is this important or does it make no difference?

Thanks for any responses.

Seems to me, as long as the gasket port is larger than the injector port, no problem. You just wouldn't want the gasket impeding flow.
