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

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.

wow, just went through all those speed websites and I want my wife to ignore the debit card bill for a while

Re: aluminum head
 

Why? is your engine tired?

Re: aluminum head
 

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.

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

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
