I recently bought a SSBC kit A123-3 manual disc brake conversion for my 1966 chevy II. My 66 was originally a 4 wheel manual drum car (single m/c with 1 line feeding all the brakes). This kit comes with a adjustable portioning valve but no metering/distribution block. If I'm not mistaken the metering block contained a porportioning valve and a hold-off valve (which delayed the movement of the front brakes. Dont I need a hold-off valve? The kit has a dual m/c, some prebent lines and an adj. porportioning valve. There is no metering valve or residual valve. I called SSBC and they said I only need whats in the kit. I've read that metering valve keep the fronts from coming on too quick and nose diving and that the residual valve keeps pressure on the drums so their movement is minimized. I'd prefer to plumb this thing only once. If I need to add this stuff I want to plan it ahead of time.
Whatta think? Add metering valve and residual valve or install it "as delivered" from SSBC?

Heres what the m/c looks like that came with the kit:

Why not call SSBC (716-759-8666), ask for Bill in the Tech. Dept.
I'm not familiar with this kit in particular, but he will be able to give you the answers. There's nothing wrog with calling and asking what you may think is a "dumb" question. There are no "dumb" ones.

I've conversed with Bill. I was a bit concerned when he said "install the m/c then attach the factory distribution block..." 1966 had no distribution block.
When I mentioned this he said "if it isnt on the car or in the kit then you dont need it". Yet I've seen posts on this board and stevesnovasite.com that talk about how adding a residual pressure valve will help the pedal feel and action of the rear drums. I know I can go back and add it later but I'd rather do it upfront if I know it's likely to be needed.

I use a stock 1970's mid-size GM combination valve on my Novas. This has the residual and proportional valves for the rear drum brakes, the metering valve for the front disc brakes. You can get these combo valves from many sources. Master Power Brakes has an excellent FAQ section, and heres some info on the combo valves:
