aluminum head
Is anyone making a relatively low compression (6:1) or less aluminum head ? of any style? Cast iron heads are getting to be too much for the back at my current state.-------thanks

Re: aluminum head
How often are you removing heads? You could always use an engine hoist to remove them and move them to a work bench or at least chest high for optimal carrying.

Re: aluminum head
I have a 7-1 Thomas head on one model A that has a modified B engine. So far, I love it.

Re: aluminum head
It's not high compression that causes babbitt problems, it is detonation. I ran a 7.4:1 Cyclone head for years with no problems.

Re: aluminum head
Is there a stock looking aluminum head being made?
Also, do any of the heads mentioned above use stock sized plugs?

Re: aluminum head
In the 60's and 70's I ran an original Thomas 8.25 aluminum head on an old worn out babbitt Model A engine.
Dwayne Helms here in Denver runs a 12.0 to 1 Cooke head on a babbitt engine. Last edited by Benson; 12-15-2017 at 03:18 PM. |

Re: aluminum head
the reason I specified 6:1 or less was to maybe reduce oil consumption. I really don't know but it would seem that a higher compression would tend to inhale more oil past the rings on the intake stroke-- that was my thought anyway.

Re: aluminum head
I would think tht would make no difference at all compression has nothing to do with the intake stroke while the valve is open

Re: aluminum head
Thanks for your reply. Any idea of how I go about buying one? Does Tod have a website?
