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) |

The port end of SSIs is rather flimsy.

QUOTE(Racer Chris @ Jul 28 2014, 05:05 PM)  The port end of SSIs is rather flimsy. I measured a set of ss heat exchangers, vendor fuzzy. I got a wall thickness of 0.080 The stock came out as 0.125 That would very strongly substantiate what Chris said. The whole point is to leave the joint at the head unmolested while pulling the exhaust. Query: is this really worth a stub joint and flange effort? Query 2: Why do we see stubs on the better headers if not for this reason? I have discovered I can make it work with ss HEs. Do I want to? |
