How worthwhile is it to match the headers to the exhaust ports?
The flanges in my 1 5/8" Hookers do not match the exhaust ports of my dart IE180 heads. They are smaller, and leave an edge hanging into the port. Mostly at the corners, where the ports in the heads are more square than round, but also some on the edges, particularly at the center ports.
I've unbolted the headers to change the gaskets, and try some fancy locking header bolts promised to never come loose. This time around, I checked Dart's website and bought exactly the gaskets they recommend, felpro 1404's. The pass side header, of course, fell out the bottom onto the floor, so I bolted a gasket on, scribed soime lines, and laid a grinder into it a bit. I'm only going as deep as the flange, maybe 3/8", and bringing it out not quite all the way to the gasket.
On the drivers side, I'd need to remove the clutch linkage to get the header out, not a fun thing.
Here's some pics. Who'd take the time to do the drivers side?
