Using David's book as a Bible, I completely rebuilt a cylinder head for 1275. Ported, polished, bronze valve guides, Jig ground valve seats, multiple angles ground on the valves, and I made custom roller rocker arms myself. I spent around 40 hours working on the head. I just finished final assembly and holy feces! What a thrill to ZOOM around in this car. The people here on this forum deserve credit as well as I gleaned a tremendous amount of information from you all. Thank you. Next is the short block with OS pistons and a lively cam. Life is good! I toast you all, cheers!!!!
 
Well done. Wish I could do that.
 
Sounds very cool!

I'd be interested to hear the details on exactly what you did and how. I know he publishes templates for grinding out the head--did you use those? Also, what kind of tool to do the grinding and polishing?

Inquiring minds want to know....
 
Cheers to you on a (very difficult, intricate) job, Tim. That head work is not for the faint of heart, or for me!

Got any photos??
 
I used a Moore Jig Grinder, normally for grinding holes within .0001" tolerances, to grind the multiple angles on the valve seats. I was able to insure .0002" concentricty and perpendicularity to the bronze valve guides so a valve lap was not needed. I used an old fashioned Fordom hand grinder to polish the intake and exhaust ports to Mr. Vizards recommendations. I used a Mitsui surface grinder and a roto-grind to grind the valves.

The shop I own is in Tempe, AZ. You can go to www.pgage.com for a complete list of my equipment and capabilities.
 
I like the whistle trick Tim. What a great idea.
 
Just looked at your shop page... man there are all sorts of shiny buttons and knobs I could push! :wink:
 
I would not call it a "trick" but a way to let the guy's know there is work for them. The sound of that whistle is very welcome in today's economy!
