All the valve guides are tight thats why I am being so careful on the grinding, the valves aren't even worn. I had the local machine shop confirm it someone re did the head before I bought the engine off of my cousin. This head came off the same 240 I got my offy DP and 500CFM carter off of we drove it back to his place after he bought the truck pulled the engine and stuffed it in my bed.


I removed some more material from the intake side, I'm thinking I am pretty much done with the first three cylinders minus some polishing i'll get some more grinding bits and a polishing kit next week when I get paid. I'll polish the exhaust on the first three then start porting the last three.
