| Post subject: | Maximum head milling? |
Is there a maximum amount you'd want to mill a head, in order to get the CR you're looking for? I'm looking at using propane instead of gasoline, and making it dedicated propane, so the plan is to run 10.5 to 11 to 1. Before I start, I'm going to try to measure everything and it seemed to me a good idea to know if I have to exceed reasonably safe limits to do this. Thanks |

I have milled up to 0.110" on the intake side and 0.210" on the plug side (angle mill) - no problems, even with head swaps after that. 33 cc's chamber. I don't know that anyone has gone further. I get 10.5-11:1 depending on head gasket on a stock comp height 0.060"-over shortblock. You can also do a combination of head and block and people have gone up to at least 13:1 with this strategy.
