Holley Hi Ram Map sensor

It’s my understanding that the hi ram is setup for the LS9 style sensor which I believe has a larger port. What is the normal method to get a standard style gm map sensor (3bar stock style) to work?

I run a stock style sensor from 05 on my hi ram. I just put some silicone on it and havent had any issues in the 3-4 years I have had the hi ram on.

I mounted my sensor to the firewall, picked up a AN fitting and ran a very short vacuum hose to it. Works good.
