aluminum head

[harryc]

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

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.

Tod is making alluminum heads. Do a search on this forum for Tod.

Also Snyder has an aluminum head:

Here is a winfield aluminum head in 6:1 or 7:1

6.5:1 too high?

I have wanted to up the compression on my stock A speedster, but I am worried about knocking the bottom end out of it.

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

Why? is your engine tired?

Snyders has a good selection.

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.

Is there a stock looking aluminum head being made?

Also, do any of the heads mentioned above use stock sized plugs?

Tod makes a stock looking aluminum High Compression head. I think Hard Times got one of the first ones.

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.

well ive not had the bottom end apart but it runs smooth and fine doesn't burn oil makes no knocking sounds

I was under the impression that higher comp was very hard on the bearings so haven't done it would like to however

[harryc]

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.

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

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