Anyone running aftermarket or custom intake manifold?

Do you know if Ron's (RAM's) rebuild kits are priced fairly? I have not had time to comparison shop.
Hmm... Maybe I won't have to rebuild it--I just got this from Joe:
Just do a compression check on all cylinders, check to see that the oil is clean, pull the valve covers, if they are clean and not full of flakey crust inside, then run it, but I would replace the oil pump.

Looks like it depends on how far you're going to get into that engine. The forged pistons definately cost. If you plan on going hi-po, and get spendy, you'd might as well build it from ground up, with new main bearings, rings, the whole nine...looks like he sells the whole engine hi-po kit kit for around $1000, which includes forged pistons, hp or torque cam, and everything else.
I think the general prices for water pumps, oil pumps, rings, gaskets are about average to slightly spendy.

You could however use a single throttle body on each manifold stub with a custom ECU this would work OK.
A megasquirt or remap an early GM ECU for which software is available on the net then all you have to do is make a water runner.
Single siamesed ports are not the best but not that bad ,after all only one valve is drawing through it at a time the biggest problem is the standard manifold and to some extent the firing order.
Nothing is imposible I know of a BMW four valve K100 motorcycle head adapted to an Morris Cooper 1298 engine with a belt drive to the cams.
Until someone tries we will never know, the Gyro guys use Mikuni's 2 per engine so why not.
