Some updates.
Professional Products
Professional products makes a manifold, # 52039 Goes for about $189 on ebay.
It is 6.060" tall, comes in a 1205 port and can be ported to a 1206. It is a very high rise intake, and would be good for 400+ CID applications.
It uses fuel rail kit # 10608, which comes with a boost referenced regulator.
The kit goes for about $185 on ebay, and comes with -6an feed and return fittings.
Victor EFI
Victor EFI manifold is 5.300" tall, and the lowest profile out of the manifolds.
Price has flexed a little bit but still reasonable. The fuel rail kit does not come with a regulator, however an adjustable regulator with 3/8" in/out is about $160.
Holley / Cutler
The Holley manifold is 5.500" tall and comes stock with 1204 ports. It can be ported to a 1205 gasket. Fuel rail kit does come with a regulator. The holley is probably the most expensive of the singleplane manifolds.
