I have a Briggs Raptor (flathead). I was wondering if anyone knows the dimensions of the stock valves?? (Inside Diameter, Outside Diameter, Height, etc.) Thanks!! ​
 
If you can find a flathead ruleset, these are called out as tech items.

My memory fails me on these details.
 
1.115 or typically one inch .
.990 on the exhaust .
That's from tech manual it doesn't have a length or I'm missing it .
If you order them for any 5 hp flathead. You'll be fine .
The valve length is adjusted to set valve too lifter clearance .
