Has anyone bought a set, looked at them critically, etc.?

I like the idea for a stock looking engine, but what has or can be done with these heads?

They have been out for a while now; looking for user or professional head porter reviews and opinions.


Too many cars, too many parts, too little coin, too little space to work in, too little time left to make it all happen! Update: down to one ride, still too many parts, a little more jingle in the pocket, gaining space, and it's going to happen this year!
