Good fit, poor to average finish

Gasket fit on this (driver) side needs revision. About half an hour with the help of a Dremel tool it was cleaned well. In general, the finish wasn't as nice as the left side, but it was serviceable. Fit was good. The steps on the manifold flange were bad. Running a faucet in it will solve the problem. You'll likely loosen the studs if you don't re-tap the steps.

Pros

Complete overhaul - including all required gaskets and downpipe fittings

Cons
