Boring the Steam Holes
What's involved with boring the steam holes into the 416 head? Is it easy enough I can do it in my garage or do i need to send them to a machine shop?
Also, I failed to mention I have roller tip Crane rocker arms with different ratios for the exhaust and intake valves... don't remember what they are but will post up tomorrow when I check.
What's involved with Porting them? again, can I do this myself or is this something i need to have a shop do?
Thanks again for the replies and I appreciate any input!
