Valve guide clearance April 23, 2011 12:55AM
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.

four on intakes five to seven on exhaust. trust me unless you like taking the head off.
