12bolt tom/ Langdon exhaust manifold heat plate kit install.

[BayArea48Deluxe]

Howdy gents so I got some new exhaust manifolds from 12 bolt tom and I want to get ready to for the install in the near distant future.. I have the heat plate etc etc. but I wanna know how would I install the heat plate ? I tried looking up older threads but only some luck.. curious as to what some folks have done …. Hoping to get pointed in the right direction

No responses so hoping to see if I can reword it..

I have the dual cast iron headers on my truck with a Thickstun intake, but I chose to forgo the heat plate.  I don't use it in very cold weather and have not had an issue thus far. 

 

So, I can't help with the install other than to say it should be a bolt on plate with coolant hoses running to it from perhaps the heater bypass connection on the head to the water pump bypass connection on the top of the pump.

I have several issues with that plate design.  Some aftermarket intakes, Offy, are porous (freeze plugs leak) and will leak coolant into the intake unless you seal it up properly.  I hae a Thickstun intake, it doesn't have that issue. 

 

Primarily though, the stock exhaust heat works to heat the intake up immediately, then backs off once the engine comes up to temp.  The plate works opposite that.

 

I don't use either in most applications, but I don't life where that might be a concern.

Tim Kingsbury did a nice write up on the subject of heating the intake. I recommend reading it, as it is full of real data not just opinions. This is one subject that many people have strong opinions on. His article, I believe in his blog, goes over all the details and why he recommends not doing it. The AoK intakes don't even have a provision for doing it.

 

But it is your car.

I don't do much winter driving, but have had late Nov early Dec runs when it been in the 20s to 30s. I have a Fenton intake with stock exhaust manifold.  The heat riser is gutted with a block off plate between the manifolds. The Fenton has a heat chamber that is compatible to the stock exhaust. So with the heat riser blocked and the manifolds connected, there still is a heat exchange between then.  I have zip tied the heater return hose to the intake for a bit more warmth when it's cold enough to run the heater.  Never had an issue during those chilly runs.

Would it be to much trouble to show me a few pictures? I live in California so the cold isn’t really gonna be a factor unless I’m like in the mountains at 4am to even be considered close to freezing on a winter day… but I would like to see it.. if it’s not a huge problem.

I have the kit and heat plate and after this thread, don't plan to use it. I am also in California with the coldest temps in the high 20s which usually doesn't correspond with my outings.

I’m glad I asked the question then Bob. Kus it helped more than just me. I didn’t wanna get it either but I said have and not need, then need and not

have. So I bought it. Cheap insurance if you will

Don't know if the pics will show much, but I will get some up in the am.

Does this help?

Thanks Greg.. but no like you said won’t see much. The plate is hidden. Can’t see it all to well. Worth a shot. Nice dual intake tho
