Anyone have Speed Master ProComp Heads with Doug Headers? If so, did they fit without much issues? I keep hearing they have better ground clearness than TTI Headers
I do. They fit fine. The hole alignment was tight to the head but they went on without modifications. I also installed mine with the engine out (Kevco Pan) of the car with the K-memeber, Starter, and trans installed. I also used Polyurethane biscuit mounts. I will note that Doug's does not send enough Bolts and washers for heads that don't use studs on the ends like stock. If you need 4 more I happen to have some.
If you have a 4 speed check the clearance to the bellhousing, mine had ears at the 3 and 9 o'clock position that interfered (as did my aluminum TKO bell) and you'll need to modify the Z-bar.
Do you have PS? That's an issue with those headers and I can explain more if you do.
Not to highjack the thread but I do have power steering and I was interested in buying Dougs headers.
Well in my case the coupler would not clear the last tube at all, it would hit. What i read was some people shim the steering box over, use an aftermarket U-joint coupler, or dent the tube. I didn't like any of those options. I ended up (to the tune of $600) bought a Flaming River drop in B-body steering column and other that having to cut the shaft shorter, it all bolted in. The universal cleared and all is good and I gained tilt. I didn't exactly want o shell out $600 for this but I get a sliding steering shaft, tilt and don't have to shim the box or beat the tube. I have found where people had no issue with the stock coupler fitting so just be ready if it does not. I will say the stock steering wheel will fit the Flaming fiver column if you grind out the key spline but the fit between them leaves gaps.

Could the header have been dented enough to clear it?
Possibly, but I didn't want to dent them. It would clear, until you turned it. Some have bent the tube over with a come-a-long, but again I felt this would compromise the finish and crack the welds.
I got a feeling I am in for some serious head aches.
Yes and No. I went from manual to power. Having power outweighed the issues. There were things I was not going to do to make it work, I found a way.
My big problem is that I have the spool mounts so it’s a bit more difficult to make adjustments.
