well i took the blue rubbe off on one side filled the slot with silicone, put it on the other unharmed gasket let it dry, melted them together with a sodering gun, did the same thing with a third one.
smoothed it out with sand paper and put it on. ran a wee bit stronger. second gear hit a lil harder mainly. no collant leaks yet and i drove it about 60 miles so i dont think its ganna leak. i melted the crap out of um to get um together

Did you notice the comments that you shouldn't do this? And you would gain more with a properly made intake BEFORE the TB?
You are taking a GREAT risk here with that coolant. Is your engine worth the risk? Is the gain (which was mostly mental and not real) worth the risk?

Just like everyone else here, I woud strongly encourage you to go back to a single gasket.
If you really want to work that angle, you could go to any local machine shop and have them machine a spacer for you. It'* just a flat plate with a few holes in the right places. A competent hand with a cad program and a CNC machine could run one up in about an hour. Shouldn't cost you too much, and with the regular gasket on either side, your risk of a failure would be just about nil.
Truthfully, though, you won't get any gain out of it unless you already have a good intake before the TB.

This isn't a TB injected application. We're multi-port.

I have a spacer on my Sonoma, it added about 1-2mpg (less than the 4 it said). I didn't feel any performance gains, but its a truck so who cares anyway.
BTW- It wasn't a stack of gaskets I melted together either, it was aluminum LMAO

I put one on my 93 4.3 and my 95 Suburban, but both were TB injected. Not multi-port.
Let'* seperate the comparisons here to make sense of it. Developing higher TB velocity from a spacer will benefit TB injected vehicles. His L27 won't benefit from it.
