Neat process.
I had a crack in the drivers side manifold of the 454 BBC in my '67 K/10 Sub. I tried JB Weld. Unlike the claims on the package side, it burned off after a while.
There were Ram Horn exhausts on the small block in my '71 GMC Jimmy when I bought it. After It sucked a couple of valves [#6 + #7], I bought a Mr Goodwrench crate motor 350. I noticed the exhausts were different. The RH one had tapped bores for A.I.R. but the LH was pre-Emissions. I didn't like the possibility of different backpressures, so I got Headman headers.
