OK, while I have the engine and trans out to work on the transmission, I
am considering putting a header on my '67 MGB. Here is the thought
process - I have a 3-main 1800 motor in my MGA with a header, and it
seems to have a lot more power. The gearing should be the same for both
(I did change the A's rear axle to an early MGB axle). Anyone know of
disadvantages of using a header on this car (other than cost) - I have
heard the stock manifold is pretty good, but I think a header would be
better. I do expect that I'll always have a little less power in the B
because of the 2 extra bearings, but it shouldn't be much different.
