Do Schumacher slant six to 340 motor mounts raise engine?

I purchased a set of Slant Six to 340 motor mounts from Schumaker instead of changing out my K frame from my Slant Six to 340 conversion. The motor has an LD 340 intake with a Holley carburetor and I don’t have enough clearance to close the hood. I contacted Schumaker and they said their motor mounts do not raise the engine. I have heard other people on the site that they raise them 1 inch. Anybody have any information on this please?
