Intake perfect fit without gaskets.

I don’t remember how much was taken off the intake side of my stock iron heads because it was years ago, but I milled the chamber side at least .060. I had test fit the intake before and thought it was going to be okay, but last night, getting ready to install it for good, it lines up the bolt holes perfect sitting on the china walls and fits flush to the intake face of the heads; without gaskets. I know I have read on here in past threads to cut the face of the manifold in this case the thickness of a gasket plus a cleanup cut. (Sorry I don’t remember which of you gents to credit with this but I did get some good info on fitting intakes from reading a couple of threads.) Problem is, my local machine shop can’t machine intakes and I am way past stripping the block back down to trim the china wall; especially just to have a void to fill with rtv. I really don’t want to strip the heads back down either so: what’s wrong with using rtv to fill the imperfections and bolt it on without a gasket? I will check some more to see if the runners line up but all the bolts start easily by hand. If I do this that leaves open using this air gap in the future with aftermarket heads.
Mine fit perfect with out gaskets so I used the steel shim gaskets in my gasket set. Sprayed them with a little permatex and silicone on the China walls. No leaks after 10 years. Cast heads and intake though.
