[Fot] TR intake gaskets

[vfracing at aol.com]

 Lyman;
Further to my earlier email: another possible cause is a mis match in the thicknesses of the intake and exhaust manifold flanges. If they are not about the same, the bridges can hang up on the stud and appear to be tight but not really pressing on the flange.  The cure for this is to either open up the hole in the bridge or weld some pedestals on the thinner flange.   Or a custom bridge....

 Lyman;
Are you certain that the manifold and head mounting surfaces are flat? We’ve seen this with manifolds that have warped a bit.
As Dave recommended earlier, the thicker high performance Remflex gaskets available from Moss or the even thicker ones from Brian at British Frame and Engine will accommodate some of this, but not all. The clamping force is low due to the need for the exhaust manifold to slide on the gasket and hence the limited bolt tightening torque recommended.
Hope this helps,
Phil Gott
