Thread: Small block head, valve measurements.

Tweet

I recently came in to a set of 350/400 heads casting number 333882. I know the valves are 1.94/1.50 but I was wonder is there a way to figure out the length of the valves stems length and width, I don't have a caliper at the moment to get an accurate measurement, is there a way to tell by the casting number more info on the valves then just what I have?

Any written information you may find could be bogus. You have no idea what has been done to those heads in the last 40 years by previous owners. Go to ebay and bid 80 bucks on any used Brown & Sharp, Starrett or Mitutoyo 6" dial caliper.

you can do any thing you like. but for work like this you can buy a cheap set of china dial calipers i had many sets over the years and they work very good for this kind of work. there as good up to .0005 of my miutoyos .place like enco has deals on some lower dollar ones
