Help I have a 1994 lexus es 300 I bought it not running. I found out it was overheated one of the 3 studs were broke off. Anyhow i got it running it steamed out the exhaust but fired on all cylinders. I bought heads off ebay had them pressure tested and surfaced. When i took it apart I mixed up the valve shims. I micrometered them and the 26 to 28 go in the intake and the 30 plus go for the exhaust valves. I put new spark plugs in and timed it but it wont start but it is close. could anyone help I am exhausted and tried all i can. oops forgot to say knock sensors were off ebay too old ones melted
