Ok, so I have the engine out and everything is going smoothly with the transfer when I realize, "hey, what cand I do to help performance?" I am installing a replacement b230 in my 86 240dl and was thinking about porting and polishing. I have heard that it is possible to do this at home and I have an extra head to practice on. What would be the benefits, if any, of doing some porting and polishing of my the head on a b230 and possible some work on the intake/exhaust manifolds? Any help would be appreciated.
Thanks,
Josh
