I know you can get them as a carb spacer, but has anyone know of these ever being used for inlet manifolds for VN heads and if anyone makes them? Have seen them avalialbe for fords in the states.
Just having a quick read about them they sound like a good idea with the inlet air temp decrease gained for a realatively cheap price.

You would need to get them laser cut from a phenolic material, it'll cost you approx $250-400. I had to get some done for my 427 Dart/Clevo.

Cool, thanks for that Bottleup, do you have any dyno results etc? Your thoughts on them?
So prob really only an opion if we organise a group by or something? Who would be interested??????

I reckon Qld gaskets would water cut you some for less than that if you draw them up in autocad - the drawing work is where most of the time is. If they have to do the measuring and drawing work as well then yeah every bit of $300 to $400 just because of the time it would take them.
Would obviously make it more worth your while if you had a few people going in on it but then again once you have the drawing, you could get a few extras made and sell them anyway if you were keen. The normal thing with setup time applies so any extra sets ordered would not add to the price very much.
Not sure if they can supply the phenolic material but you can get that yourself and they would water cut it no worries I have used them to water cut alloy bits for me of a similar complexity to the gaskets you want - I gave them the alloy and the autocad drawing and it cost me about $75 to get them all cut out.
I wouldn't expect to see huge improvements but every little bit helps.
This link below is the closest to a before and after dyno comparison I have seen for these phenolic spacers - unfortunately the results are clouded by the fact they changed to underdrive pulleys and a different exhaust crossover but it shows a 20HP improvement - I suppose that sort of puts a cap on what you could expect to achieve.

I am going to get a set and disconnect the coolant lines from the throttle body too just incase it does make a difference :-)
