Hi John: Thanks for the information. If I hear you correctly then I should be able to add a manual choke and it should work just fine. The only other issue would be that the hot water will not flow to the base of the carburator and given that I do not drive this car in winter then perhaps that is not an issue. Your opinion on these two issues would be appreciated. I would get aluminum heads but I have heard stories that it is hard to find ones that are not warped. I found the torque settings to be 25-30. take care, Walter Gerrard
