You have great advise on the dowel-stud upgrade, much more positive clamping. No time this round, engine getting rebuilt for BajaTR3 after LimeRock. Will do both TR4 engine in process and BajaTR.

All sealing surfaces are good & flat. Going to start from scratch. Remflex gaskets, nice 3/8 shoulder bolts I have, fab new cross clamps, service headers even though had no exhaust leaks.

<p>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. </p>
<p>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.</p>
