I'm refurbishing a set of HIF-4s for my dual carb conversion. I have an old heat shield that I'm also cleaning and painting. One of the heat reflective pads on the back side is gone and the other was barely hanging on. What should I replace the material with? Can I buy it at my local hardware store?

Thanks!

Someone here has made up these pads and they look good. I think it is projectMGB"??

The old pads are asbestos and NLA. Worth a search here.

Eric has the material. He's on the forum as ProjectMGB.

Eric, seems to be MIA, hasn't posted since August and his website talks about the material but is short on details of the manufacturer, or name of the product. I'll send a PM to see if he's still around.

The new B Hive/Moss ones come with two strips of header wrap riveted on them.

Eric - I believe that Eric Sorosiak also sells his heat shield material on Ebay. I was quite pleased with the way the new pads fit (that is my HIF4 heat shield pictured on the May 4 post referenced above). You are lucky if your shield is not cracked. I had to have mine welded.

Hi : I've had this problem before and used a thick nomex/fiberglass tape made for wrapping
exhaust pipes. I found rivets with big heads at a hardware store to secure the
tape.

This works and can be cut to any shape.

The stuff is Fel-Pro "Fel Ramic". I think it's ceramic fibers with a metal backing and it looks sort of like exhaust manifold gasket material. P/N 3009, A 12" X 28 1/2" sheet 3/64" thick. There are other thicknesses shown in the catalog and they are all four didget numbers beginning with 300.

I used two layers of adhesive-backed air duct insulation wrap you can find at Home Depot or Lowes. I then used a top layer of High-Heat Copper Silicone and Heavy-Duty aluminum foil. I ran each layer completely across the the back of the shield. Thus, the heat transfer is spreadout more evenly and there are no hot spots across the shield. Plus, you have something to dissipate the heat from the center exhaust branch which is of course hotter due to the siamesed exhaust design.

The result is a much cooler shield (verified by IR temp. guage) for very little money. I also attached a piece of the insulating wrap to the underside of the intake manifold cross-tube since it is directly above the center manifold branch. Anything to keep the intake temp. lower...

Where does one get High-Heat Copper Silicone and Heavy-Duty aluminum foil?

You can get High-Heat Copper gasket sealant at Advance Auto, Napa, etc. It's made by Permatex and is readily available. The heavy duty aluminum foil can be found at any grocery store. HTH! smiling smiley

Oh. Somehow your first description sounded more exotic than that.

Thank you.

As a few members have already stated, I have replacement insulation available for both HS4 and HIF4 setups. The ceramic-based insulation is very similar to the original insulation in thickness and color. Also, the brass rivets that I include with the HS4 sets are nearly identical to those originally on my heat shield.

I have details at:

http://www.geocities.com/project_mgb/heat_shield.html

Unfortunately, this link often doesn't work if several people have tried to access the website within a short period of time (the free Geocities site has a data transfer limit). However, you can check out the MGBE post:

or email me with any questions at project_mgb@yahoo.com

Thanks,
