MG TD TF 1500 - Head- Rear cover plate size?

I am looking for the dimensions of the XPAG head Rear Cover Plate. The car is garaged elsewhere, and I am trying to get motivated on a heater project. If anyone can easily get that info for me (height x width) I would certainly appreciate it. hanks-

Tom Lange sells some good thick ones which are a great replacement...

Geoff-
Yes, I wish I had one handy, so I could measure it. Then I would know what size the plate I need for my heater project would need to be. So, good thinking, if anyone has a gasket for the plate, getting that info (h" x w") will do.
Thanks-

N Tesla, the size of the plate is 3 7/8" x 2 7/8" or 100mm x 72mm.

the Moss replacement plate measures 3 15/16" wide and 2 15/16" tall at the outer edge.

The gasket is 3 3/4" wide X 2 3/4" tall at the outer edge.

The gasket holes measure 3 1/16" wide X 2'' tall on center.

"Note", since gaskets shrink some times, I would want to measure the actual head or the old plate to confirm before I drilled holes.

Great, thank you. Following my MG mentor's lead, I am using 304 stainless with a copper fixture. Such copper fittings and 304 have the same heat/cold expansion/contraction characteristics. Well, very close.

Nick, you might want to do some archive checking. The back of the head doesn't get great reviews as a connection point for a heater. Bud

There's been a lot of debate on this and I eventually decided to take mine off the thermostat elbow, which is the hottest point available. I also ran the pipes under and behind the manifold, because it looks better (less clutter) and probably picks up heat too. I also used 5/8 thinwall stainless pipe to run the connections, and avoided all 1/2 fittings, to maximize flow. Hard to know if all that will make much difference, but the result is certainly plenty of hot air :)
If you are redoing your heater system I might suggest you look at not going through the firewall holes provided, and instead look to build an easily drainable system by gravity. It will make your life easier at the end of the day, avoiding messy heater spills when you have to remove it.
Good luck with whatever you decide to do!
