The Stovebolt Site Forums The Shop Area Engine Shop Quick heat plate question

I purchased a heat plate from here for my 250 but need some clarification on installing it. When I bolt it to the intake manifold, can I only use the gray rtv or do I need a gasket?

If I need a gasket, what kind and do I use the gray rtv on both sides?

Thank you for any help!

Anyone?

Backpayne, I think you may have to look for dealer add on accessories to find it and perhaps instructions for mounting. I have see this topic here some time ago but my search has yet to find it...... Be patient. I know someone here knows and may even direct you to a picture.

I know nothing about a 250 ci engine, or its intake manifold.

Here is a quote from a Tom Langdon write-up that someone linked to years ago regarding a 250 intake's heat plate.

"Our heat plates are not sold with a gasket, but a gasket is definitely required. Use the gray color RTV or make a paper gasket and add gray RTV (ideal) or a factory type gasket with RTV."

I take it you mean a heat plate that goes on the heat stove on the intake when you put headers on, correct? If so, you use a gasket, no RTV. RTV will simply burn out, causing a leak.
Something that I wondering about, you mention in your post that you bought the part from this site? AFAIK, the site does not sell parts, other than the occasional license plate topper. I'm inclined to think you might be confusing this site with Langdon's Stovebolt , which is understandable given the similarity in the names.

Looks like Tim posted the same time I did. Reading his link, I forgot that Langdon uses water for their heat, rather than exhaust. RTV will be fine with water.

I do not use water/coolant, but I have used it in the past (235/261).

With exhaust heat to the plate, I think use the RTV (hi temp - red (650F) or copper (700F), I guess)

gray : 500F

Thanks, Guys. Regarding buying from this site, I was wrong. I bought it from Langdon's Stovebolt site.

I'm new to this inline 6 and want to make sure I do things right the first time.

Thank you, again!

Not sure if this fits with this thread, but here goes-
I'm using a 292 replacement exhaust manifold on a 194. There's no provision for a heat riser so the exhaust routes right onto the bottom of the stock 194 intake manifold. Haven't got too many miles on this rebuild yet, but it seems like it might be working out. Anybody have any experience or ideas on this issue? Langdon's heat plate for intake manifold info says you need "moderate" heat transfer to the intake! This set-up would be a bit more than "moderate."

A lot of the heat riser valves have rusted or rotted off without any problems with running. The valve doesn't seal anyway, so I would bet it's just as hot. I suspect the valve is there mostly to direct the gases out the hole.
