Well, I have this set of 5.7 heads from an early (2006?) motor, and would like to clean them up a bit. But as the title of the post says, I don't know much about these heads, or porting.
So the plan is to get what info I can here, and tread very lightly with the die grinder. Anybody care to share?
My thoughts are don't change any general shapes, just clean them up and remove any ridges left by machining operations. Because this is going to be a carbed motor, I plan on leaving the ports on the intake side rough, using as course as a sanding role as I can find. The heads will then get sent out for a valve job with stock valves.
