I edited some of my detracting posts, Im a real dick some days.
But since you have hands on these heads...... whats the report card look like?
Like I said above this was a freebe job for a friend. It is still mounted to my flowbench as I ended up in the hospital with a few health issues and I'm very limited in what I can do until hopefully getting straightened up. If my health returns I will have a set of my own and will dig deeper into them. Th four valves that I removed so far feel great as far as valv guide clearance. I told my friend that if he wants to come over some evening and tear them completely apart I will assist him so he can as a 22 year old learn the process. I truly like what I see so far and will update when I have more info. This head will go 300 plus CFM with little work
