[Fot] TR intake gaskets

[yellow04]

My money is on this one... Blowing out the bottom of the intake gaskets
means you didn't get nearly enough pressure (if any) from that pesky
lower mounting stud and clamp. I have found if you use anything other
than a stock intake manifold and stock exhaust manifold, you must
scrutinize the area where the clamps will sit to ensure the height is
very similar. Or, modify the clamps by welding on something to make sure
when the clamp rests on the appropriate bits of the intake and exhaust
manifold, when the nut is tightened it puts equal pressure on both
manifolds. Obviously, the mounting face on each manifold needs to be
flat. Assuming you have everything in order, there is no reason a stock
manifold gasket will not work, I have run them when I could not get my
hands on the HD gaskets and they worked fine for me.  

Last thought, the nuts that hold the manifolds on are notorious for
loosening up in time, and especially after the first few heat cycles.
And with everything installed, getting to the two bottom nuts can be a
pain. But, failure to keep them properly torqued leads to blown out
gaskets.
