I have decided to take the heads off the type 4 engine. Everything I do lessens the cost that my engine guy will charge to rebuild the engine because he charges by the hour and he is very fair in the accounting. This engine which is a Raby kit built engine with heads that Jake Raby built. The heads are super nice with some porting work done and larger valves. Stainless steel 42mm Intake and 36mm exhaust. I went ahead and slipped no. 1 cylinder off and it looks very good. No scoring and some of the cross hatch still visible. I did find that the two top rings had the opening both lined up at the bottom which isn't ideal. Chris said that one of the cylinders had low compression and the engine was burning some oil. I measured the cam lift last night and it is .435" which may mean it has something like a Webcam 86A grind with 290 duration. The inside of the engine looks great and is nice and clean so the dirt and dust didn't affect it much. The cam lobes look perfect and the lift is nearly identical from valve to valve. I may get by with a top end build and have a super nice type 4 engine. I am very happy with what I am seeing now.
While writing this a huge storm has blown in. (I live 25 miles west of Louisville Ky.) and is dropping some serious hail. My poor Crossfire SRT-6 is stuck out in it. The transformer near my house just blew and my trusty natural gas powered generator has kicked on and switched my home over to generator power. I had to have this generator because my basement will flood if the sump pump isn't running, ask me how I know this.
More to come on the engine. Enjoy some engine ****.
