When I built this truck years ago I did not know about remflex exhaust gaskets
Thanks to
@Rick I learned about these and have been using them only ever since
I have tried all gaskets with the torque monster headers and they can be very difficult to seal. Not when you use remflex
So I have been using remflex part
Number 3028 for a couple of years now
Then I saw Tim
@vroomzoomboom mention a 3003 part Number for our square port 302 gt40 heads and TMH
So I got a new set of Remflex, both 3028 and 3003, you are welcome lol
Let’s compare

The Mr gasket ones that were on the engine show many signs of leaking,
Typical with obx or tmh and your standard gasket
The header bolts were very tightened a few times after heat cycles, and the truck sounded good.., but still evidence of leaks

Both sets fit the head very well
The 3028 gaskets have a slightly smaller port which does “catch the edge” of the torque monster port. The 3003 port fits better, and still has enough material to seal.
Anyone want to buy a nib set of 3028? lol I will be using 3003 from now on… thanks Tim!!
You guys with race versions of the tmh (larger primaries),
Boost, or with aftermarket/ported heads will really benefit from the larger port holes
