Hello everyone,

I have a set of 441 heads in my shop that I would like to put on my truck. Their in great shape, they just need some cleaning up. I was wondering if their are any websites that show how to do a porting job. I have the basic idea down I would just like some clarification with pictures. Also is there any thing that I should know specifically about the 441 heads?

Im going to put them on my 77 chevy 3/4 ton PU. The engine is stock and only has about 100k miles but I think the valve guide oil seals are bad so I figured why not put the 441 heads on and get some more power. I don't remember the casting numbers on the 77 but they where supposed to be some of the worst heads made, tiny valves and crack prone.
