I've got a set of GT40's that I am going to use on this LTD, but want to put something into the EGR port on the one bowl, anything I can use to fill it?
Blocking it at the head/intake by welding the intake hole is plan B, I was looking for something I could fill the hole with so that I can shape that bowl to match the rest.

Lead or Aluminum will work.

I use to use aluminium to block the heat riser passages in BB heads. Use to melt it and pour it in. I think lead might melt?

i have filled the heat crossover many times. i use a zinc alumn. alloy from mondello. melts easy.

Mc Master Carr sells Zinc i melted alum for mine zinc needs less heat to melt.

I usually pound in something that I shape a little to contour

and then pour in the filler.

in the oldendays, we qould just pound in a screen like and then plaster of paris or cement..

ZA12 It is a zinc aluminum alloy that works very well.

That's kind of what I was thinking too..I've heard from one guy that fireplace grout would work, it makes sense that it would hold up. I want to be able to shape it without phucking up a burr.

 

[Super_Dave]

I wonder how this would hold up, supposed to good for 2K degrees.

you can just use red rtv on street strip stuff. marine/endurance is a different story. I know its its not as good but thought Id put it out there

I've cut up old aluminum rods to melt. Some guys I know used old pistons.
