Anyone finishing up an alky 4mm stock motor and need a cheap head?

We just tested a new cut for a stock head for a 4mm bike with 795s. Ours test bike was only a dune port with toomeys so we would like to get it on a bike with more aggressive tuning and possibly Shearers or CPI OOFs. We are looking to send the head to someone that preferably drag races and familiar with tuning. Head is setup for alky, 795s, Cometic or thin base gaskets. Dyno would be a plus. We will send the head free of charge for testing. If you like it, price will be 75 bucks, if you're not happy or just don't want it, send it back, no charge.

 

 

If interested, shoot me a PM so we can chat and we can get this head out.

 

Thanks

Got any 68mm ones for a cub?

 

 

 

We have cut several for 68s but they make me nervous because there is not much surface area left. We have not had any failures yet though. Have not pushed a 68 to alky specs though either.

We have had several questions on alcohols so thought I would clarify. The head was tested using Methanol. 100% Ethanol can also be used with a little less timing but E85 should not be used with this head until we can do some tests. We will more than likely have to tune E85 with additives to get acceptable detonation suppression.
