Valve guide clearance
|
We are doing a new head for an alcohol tractor and was wondering what most people use for valve guide clearance.
Just curious. Thanks |

That seems like a lot. Since alcohol will tend to burn cooler, probably stick with the stock specs. Maybe a thousandth or two looser on the exhaust side if you are really really nervous. |
