Good thought. After searching out this issue, I see that the Weiand 7510 isn't the best choice for a driver anyway. Heads are for a 2 bbl, so I'll start looking.

After these discussions I'm leaning that way myself. Hard to justify making mods to an engine to accommodate a bad manifold. I really appreciate FABO and it's members for helping solve problems like this.

That's correct. It slides on the china wall back and forth, and the cast iron manifold fits with no slide.

Thanks DartSwinger and Dicer- For grins I measured the distance between the rails on both manifolds. The Weiland is exactly 1/8" narrower than the cast iron manifold. 7 5/8" vs. 7 3/4". I am now suspicious of the Weiland, as I look closer, the rails have fairly deep scratches running...

I re-read your post- saw you used a silicone bead on the china walls. Got it.

What did you use in place of the cork gaskets?

It is used and I don't know much about it. The rear water jacket seals on the back of the manifold show some corrosion, so I can assume that it has been used, but the seller didn't know much about it. It could have been machined.

Cast aluminum is quite brittle, so I was very careful tightening. Your comments help- if all aluminum manifolds are like this, then I need to make this one work somehow.

The pins are not in the block china walls, so that's not a problem, but it was worth checking at this point- thanks.

Engine is a 74 Dart 318. The block had both locating pins for the heads, no locating pins for the manifold- should there be pins for the manifold?

I shared the same concern about coolant in the valley, and there was some in there, but don't know if it came when I lifted the manifold off. Sealant is a possibility but the gap seemed pretty large for a sealant fix. That's why I'm gathering thoughts- thanks for yours.

I bought a used Weiand 7510 aluminum intake for my LA and cannot get it to seal. The rear coolant ports both leak. When I removed the intake, the metal gasket ridges were not flattened, and it does not appear to fit. As a sanity check I compared the fit on the head with a cast iron 2bbl...

I know the potential for that is there, but fortunately I'm not upside down in this one yet, but it ain't over! That's why we started with a "driver" and not a concourse candidate. That was smart.

Ouch! Nice thing I've found, even the parts I've bought by mistake seem to sell, which lessens the cost of my education.

Being a novice, hindsight is a wonderful thing. Sometimes those lessons are pricey, but we're learning.
