Snyder or Thomas head

Too hard to crank with the starter is the biggest crock I have ever heard.
Beware of that guy.
I have run B engines with 11 to 1 compression on alcohol and they start right up on the starter just like a stock engine.
 
It will be interesting to see what you find. There are almost no high compression heads made for the Model B water pump.

I am only aware of three that were ever made, all in the 1930s and 40s, all cast iron, and all made outside the USA.

Vince, at Hershey this year, Dan Price had a new flathead on his table that had the 3-bolt water pump. I did not inquire about it but I suppose you can addition to that admittedly small list.
 
Now I'm really curious as to WHY there weren't a lot of high compression aftermarket heads made with the bolt pattern for the B water pump. Today, it seems that lots of guys are trying to get top performance out of there bangers, and that B Bangers are quite popular. Wasn't that always the case, given the improvements in that engine over the 'A'?

Anyway, now I'm a bit skeptical about that "aftermarket high-compression" head that I'm going to see later today. It's probably a Ford Model B head, although the guy said that he didn't think that it was made by Ford.
 
The referenced "high Compression head" that I looked at this afternoon has me a bit uncertain. It has a large "C" cast on the top of the head, but doesn't say Ford anywhere. Instead, it has "3M" inside a rectangle, and right below that is a cast designation "M-6050". Elsewhere on the top of the head, it has what looks like a screw head casting followed by 16-255. Finally, it takes spark plugs of a smaller base diameter than Model A spark plugs. Anybody have any idea who made this Model B style head, and whether it's a desirable head?
 
Thanks, forever4. I guess it's about the same as a Ford-made Model B then, compression-wize. Probably worth the $100 the sellers is asking.
 
I have been running the Thomas 7 to 1 head on my speedster for going on 16 years. I have 9,000 miles on everything. Runs great!
 
Another thing to consider is that this car is in the U.K. and could have the smaller cubic
inch displacement motor in it. If it does you could be lowering the compression by
putting on an aftermarket head. If so you may want to go to a U.S. spec motor.
Does any one know the chamber cc's for the smaller displacement motor?
 
I read somewhere that the small engine was 2.2L while the US model is 3.3L

Good knowledge! Luckily its a U.S motor!

The small UK (and therefore european) engine has a displacement of 2043 cc and the standard engine ( US and european ) 3285 cc.
1928-31 Model AF makes 28hp (at approx 2600 rpm ? ) but 1932 model BF (or ANF) 40hp (at approx 3100 rpm ? ).
The model BF is quite different with its valves which move (tilted) near cylinders. Two effects of this : little combustion chambers and more water around combustion chambers and intake/exhaust.

Why not make an HC head for these engines ?...
 
Hi,

Im looking at getting a new higher comp head for my newly bought 30 sport coupe. Il need to get the head shipped to the UK.

I see that Snyders to their own branded head but also sell a Thomas head (which is more expensive) I will spend the extra if its worth it.

What are the differences and which would you rate higher?

Im new to all this, so apologies if its been covered before.

Thanks

Iam trying to make the same decision, which head, Snyders 6-1 $325 or Lion 3 $569, I prefer the 6-1 cause it looks better, but would like a 7-1, just wish that new 7-1 cast iron by Tod was out next month cause that would make my decision.

Depending on how the core shop does, it just might be.

Now that is good news - lets hope all goes to plan, i would love to have the new head fitted for pendine sands this year. Fingers crossed.

My original post was between thomas and snyder, but once i was aware of Tods Winfield my mind was made up.
