I just wanted to post up pics of lower intake clearancing for MMR HCM.
I probably removed more material than was really necessary, but i did what I did.
I found that a file and hack saw worked best for me.

Depth of intake space above freeze plug is ~10mm.

Height of MMR fixture is ~9mm.

Then the Lower intake gasket will help to clear it more.

I just did one for free when the engine was out with a spare crack pipe and some heater hose. Pretty sure the Lethal and On3 copy of the Lethal can be installed without hacking anything...

yes..I had a kit that I made and it was using freeze plugs and brass fittings,
It didn't require any filing either. It was very low profile as well.

I didn't feel like drilling a freeze plug and threading and soldering brass fittings in; so I spent the coin on the MMR.

I couldn't find any pics for this MMR install concerning the filing; so posted this up to share.
It's a fairly popular mod.
