Best deal on burrs I have found is ebay. I use an electric die grinder, $40 from HF a few years ago. It's LOUD but works great. Use a router speed control (another $10 or so from HF) to turn it down.

You will need a variety of carbides.HF used to have a decent set for the chambers and the edge of the ports.The long shanksget squirlly out near the outside and jump around.

This looks like an excellent book. I'm going to get it for myself.

I have a couple David Vizard books, and he is a good author with lots of time behind a dyno to present his data, theories, and changes in his books.

I do have the Burgess&Gollan book, it's specifically meant for the British motor crowd with not much that can be used directly in the US, most of the presentation works directly with MG, Austin-Healey, British Fords (they give data on the 351, but USA Ford has better data due to direct factory support of that engine over the years). I would not recommend this book for our application.

Dust mask, nitrile gloves and hearing protection is my uniform. Air die grinder is loud, and cold in the cooler weather.

How my progress? Does this look right? It's not done yet just checking.

Got flapper wheels? That will polish it good. The valves need to be un shrouded. Possibly set the larger valves on top of the old ones to determine how much to remove for un shrouding.

The rough areas around the edges can be done with the right shaped metal bits.

You went 2.25", is that the max bore on the outlet? Looked and searched for pics of the outlet etc but no luck....end jack...

How'd this turn out? I'm sure the burr bit went a bit faster. Should post updates to show a guy like me (never ported a head either) that it can be done and some tips.

Sorry it went very well. I did not need to port match as my gasket was already very well matched so what I did was mostly clean up. It is not as good as many others would have done. I don't have any pictures at the moment. I will post more pics as soon as I get the head back.

What I did was grind down the casting seam along the interior walls of the valves and the ridge directly in front of the valve stem inlet. Then came back with 80 grit sanders and "polished" everything I could touch. I also ground down any casting marks. I found several warts in the tunnels.

There are better ways to do it and with more experience I may have gone more daring but I just really wanted to focus on air flow clean up.

It looks like this was bumped up for my benefit also. Thanks. Another question is whether it is better to use the head that will come with the hydraulic motor in its stock form, or use the drool tube head on the existing motor which I have spent considerable time porting, and which has oversized valves? Using the existing heads will save time and money. I also cc'd them with the plexiglass and cooking oil trick. Does porting and over sized valves hurt efficiency if the engine will never see over 3500 rpm?
