The Stovebolt Site Forums The Shop Area Engine Shop Bolt Boss Removal

I'm sure this topic has been cussed and discussed repeatedly, but I haven't got the answer to my question, so here goes.

I am going to start the rebuild on my 250 I6 next week end. I plan on cleaning up the ports a bit using the info on the Standard Abrasives web site as a guideline. I am using stock valves, a mild cam, V8 pistons, split exhaust manifold, and a stock intake modified to receive a Holley/Weber 5200 without any adapter. I've got a bunch of jets for the carb so I can get it tuned just so. Now here's my question; when I clean up the ports should I reshape the bolt bosses to a more streamlined shape, or leave them alone?

Thanks in advance for your help, and for those of you who pop off without being helpful, God will forgive you, but I may not!

Can't recall what it says, but Santucci's book covers porting the 250 well.

I think that adding lump ports is more important than messing with the bolt bosses. However, polishing the roughness out of the casting is better than nothing at all.

You can borrow my Santucci book if you want, boo.

Josiah -- I would love to take a look at that book. I'm always hearing about it, but I hate to order something I've never seen. Send me a PM and we'll see about getting together.
