B head inquiry.
I was contacted about an old post I made about B heads. The question regarded making one that was basically stock looking yet having a high-compression chamber. Today I took some time to do a little model work in that direction. I figure I would use the Snyder 6:1 chamber with all its internal strengthening ribs. They would be available in iron or aluminum.
It seems these would be in far less demand than other heads and would be more expensive due to less interest. But, if enough people are interested a short run could get pricing down. Note: The picture shows an incomplete model. I need to place the spark plug bosses where the chamber dictates. Tod |

Re: B head inquiry.
In my opinion, a Model "A" hi-compression head on a Model "B" engine is the way to go. I agree that the market for a Model "B" head is risky.
I have been running Model "B" engines for many years with Model "B" and Model "A" cylinder heads. It has been my experience that Model "B" water pumps are relatively scarce and pricey. As for reliability, the leakless Model "A" pumps are far superior to what's on the market for the Model "B." Parts for the Model "A" water pump are much more prevalent, and less expensive.

Maybe you could go one up and create a 6.5 head or 7.o while your in the start up stage Tinkirk/Terry |

Re: B head inquiry.
If you are going to all that trouble, I would suggest using a Winfield chamber, maybe the crows-foot.

Re: B head inquiry.
This is where I am so far. The top is finished and ready to cut. I modified a Winfield crow's foot to get a chamber. Not sure if I like it, though. I think it would need testing.

Your comment about the location of the spark plug bosses scares me. I would think the only market for the head would be to people that want to pass concourse judging but want a little more power. Relocating the plugs would defeat this. Also on a restored car the distributer is connected to the spark plugs with brass strips instead of wires. Changing the location of the plugs would probably result in these brass strips not fitting. You should also consider placing a block "C" on the head as was done on the originals. Charlie Stephens |

Re: B head inquiry.
With my Winfield Redhead (7.0) with crows foot combustion chambers the spark plug is between the valves, not over the intake valve. With higher compression ratios the part plug location becomes very important. No I can't use the stock distributor cap and number 3 spark plug does interfere with the distributor advance-retard arm.

Yes I did misunderstand. I assumed you had a revised combustion chamber and were going to relocate the plugs to the best location for the revised combustion chamber. Charlie Stephens |
