Can any one out there comment on the idea of cutting off the 6 inches or so of the heat exchanger where it meets the heads and adding flanges there so that the exhaust can be dropped without disturbing the head joint?
I have a spare set of heads so I ws thinking of mounting the heat exchangers, slicing and then tack welding the flanges while still in place. I was thinking of using V flanges with rings as well so you could still get to the head studs with a socket. Ideas? (IMG:style_emoticons/default/popcorn[1].gif) |

i think if you take 6" off of the head ends of the heat exchangers you'll be into the bottom curve of the pipes. you're going with stainless?

Yeah, I would say that is correct. I have experience welding stainless, and thought it worked well. I might fill the tubes with argon. The welds will be to flanges, not directly joining tubes. The curve is a problem. One solution would be to cut the stock stubs off at the point they start to curve and join to a straight point on the new stainless. That way, the HEs would drop down and that might magnify the problem. I ordered the flanges, but I have a lot of things I never used... |
