HI RatPack,
i'm not using Raised Port heads, and Jere didn't mention any problem using the 105 design with stock heads...in fact he did confirm that they work with the stock heads... I don't know if the column arm is only a problem with the raised port heads or not, but he did confirm that the arm is an issue in my case, so i'm assuming that it doesn't matter which heads I use....
DUH... forgot about the key Provision. i guess I'll just have to cut it off and get another column if I ever want to put the stock parts back on.
the original 106 only comes now in 1 5/8 and i wanted 1 3/4 so that rules out the original design.
the Hooker SuperComps that you spoke of are 1 7/8, which would be fine for a 406, but the ones I have experience with are 1 3/4 and I know for a fact that they hit the steering linkage underneath the car... i've used those headers before and aside from that issue, they are nice... the other problem with hookers, as i've said before (at least the 1 5/8 and 1 3/4 versions are that they hang rather low... much lower than the stahl, Dougs, or any other header i've seen.)
the 1 7/8s look nice, but they are way to big i'm guessing for a 302 street car... even if i'm running the 140 cam...
when Speaking with Jere, he claims that his 1 5/8 (model 106) made 25 more HP than the orignal 1 3/4 bill thomas headers from 1967.. he said that the big reason was the fact that Bill used 2.5"radius bends, and his headers use 3"radius bends... i'm not sure how much of a difference it makes, but Jere seems to really know what he is talking about.
if I don't go with Stahls, i'm gonna get the 67 or 68 repop headers... i just didn't want to pop for that much money... oh well.
Thanks
Aaron
