MG MGB Technical - Porrting and Polishing head

Anyone have an articale on how this is done? Also if anyone has done it to a stock did you notice a bid difference? Thanks

Lots of info in the archives on this. I had my head done by mike brown. He did a race port polish job. The difference was like night and day. It really made use of my weber, and it feels like it can really go now.

My head was done by Peter Burgess to his Fast Road specification. It was money well spent. The difference was like night and day. He states that on an otherwise-stock engine the Fast Road head should produce respective increases in power output of 25% @ 3,000 RPM and 30% @ 5,200 RPM when using K&N airfilters. I've been building engines for roughly thirty years and can tell you that this is the one thing that you should leave to an experienced professional specialist. Don't try this at home. Chances are that you'll turn your head into scrap metal. Peter has a website at http://www.mgcars.org.uk/peterburgess/

Hello Steve in Virginia,

Once again, many thanks for the article you sent me. Did send you an "reply-email" ( at Bigface and so on.. )the other day with a couple of questions. Did you get it or are you drowning in emails from happy people around the world reading your article?

Best regards

Anders

The Emails are coming in at a steady pace, but I'm not overwhelmed by the sheer volume of them. I sent you an Email on 11/28 with the two attachments.

Steve,

Did you send Peter your head? I want to get a feel for shipping costs from the eastern US.

Thanks,

Yep, as I said earlier, Peter did my head to his Fast Road specification. He presently charges 330 UK Pounds for this, which at the current exchange rate of $1.41US per UK Pound, works out to $465.30. That's a real bargain by any standard. The head dictates how fundamentally well an engine breathes, and that's what's crucial in terms of power output. As for shipping costs, hold off on checking prices as they're high right now due to the Great Christmas Rush, but come mid-January the rates will be really low due to the return of Old Man Recession. Of course, if you insist on Overnight Air delivery, expect to pay for it. You have until Spring, right?

Steve,

Thanks for the info. I should be headed to the UK in March for business. Maybe I'll just take the head with me. I'm sure I'd have no trouble explaining that to airport using airport transfers tonbridge security. "But this IS my carry on..."

Steve, Hate to bother you with this... maybe I should contact Peter. For 330 pounds, what treatments are included? Does it include a complete rebuild or just the porting job? Does it include seats, guides, valves, springs etc??? And how long did it take? Thanks for the info. -Brian.

Peter has a website at http://www.mgcars.org.uk/peterburgess/ where you can check all of the specifications for all of the different stages of headwork that he performs on heads. The Fast Road specification includes bulleted bronze valves guides (to get rid of the extra heat that come with the extra power output), 3 angle grind on the valves (stainless steel) and seats (which are lead-free tolerant inserts), opening the throats of the ports, blending of ports to the seats, polishing of the ports, modifying of the combustion chambers, and removing all sharp edges of the ports and combustion chambers. Peter will install valve springs matched to suit the camshaft that you choose to use (cost of springs are extra due to varying costs of different sets of springs necessary for different camshafts). All in all, it's a bargain.

Thanks for input.
