What is the name of the tool used to ream out valve seats for larger sized valves?

The only thing I can find is a valve lapper, and I am fairly sure that is not going to work properly for upgrading valve sizes.

I am also curious what tool is used to measure valve spring compressed height and max lift n stuff.


Thanks !

 

I'm gonna say valve seat cutter. Other might call it something else.

And a "valve spring micrometer" "valve installed height micrometer" ....

 

i believe it is called a bull nose or bull hog. something like that

 

to measure installed height i use a snap gage and dial caliper, to measure lift depending on how you want to do it a dial caliper and calculator, or a dial indicator

 

Thanks y'all, I found them Now for that next paycheck to roll around... found some chinesiums, but I doubt they'd be accurate, or last very long.

 

you got that right, buy quality tools, take care of them and they'll last a life time. i like starrett precession tools and there is never a question of them being accurate. ebay, flea markets, and garage sales are great places to find good used tools.
