Jon..yes the LD340 was a very a good intake, they are quite sought after down here.  I think you can block off the heat riser quite easily?  I do know that it can be done in the cylinder head as well, where the exhaust gets pumped into that U shaped area. Jon, if you are on a budget, here is a manifold i saw at the same place, KMJ Performance - i was going to buy it but it put the postage price up too high. For $150 it looks ok. But made in you-know-where.  The AirGap down here are up around $600+

in any case, this is the manifold i was thinking of that i had hidden away, it is called a Victor 340 (Edelbrock) and is the Air Gap design - just wondering Eddie if this is the same manifold as the AirGap but a different name? If not, do you know much about these?

 I would save my pennies are better yet E-Bay the Victor 340,(single plane), to a racer,,buy a AirGap and retain the torque while increasing the HP....I love mine!!

 as soon as i started reading your post i realised, of course, this is a open plenum single plane, the Airgap is a dual plane.  Thanks for reminding me -and good idea, i will put that inlet on the market (not ebay though - they have #%$@ me around too often with selling) and use the money for an airgap.  I have a sneaking suspicion that the link i told about in the last post is a chinese version of the airgap, except it doesn't have the gap at the front, only underneath and at the rear.
