I would be very interested in seeing what you are checking and honing guides with?
I have north of 2K just in the equipment to achieve those two task.
Keep in mind that I'm just regular guy with an old car. Nothing I can do at home is to machine shop/professional standards. My comments were strictly as to 'what can a guy in his garage check on ootb heads'.... That being said, if I buy a set of heads from wherever, this is I could do at home.
$15 digital micrometers
$15 hole gauge set
$10 gage pins .342 .343 .344
$35 digital micrometer
$20 dial gauge
$10 11/32' flex hone 120 grit
$8 lap tool
Measure installed height of springs. Dis-assemble heads. Measure valve stems. Measure guides with hole gauge set. Use gage pins as a 'go no go' test. If guides are tight use flex hone. Lap valves, check for evenness of lap marks. Bounce test valves.
As an example, I picked up some older 113 heads...obviously nothing fancy or impressive. I was able to check everything I listed and made a determination the heads were good to go using the tools listed. (guides are within spec so I didn't hone them).
You all are pros and I'd never dis-agree with you. I've learned a tremendous amount just 'lurking' and will continue to learn.
