With my valve machine it takes no more time to cut a multi angle seat than a 2-3 angle seat
then a little had blend at the bottom and standard valve job is done
so why not
I get all the throats the same, two top cuts (30 and say 15-20 if necessary and room), open up the chamber
one operation
Most lifters come with oiling today so why not buy a little reliability on the rocker cups or balls with open ended pushrods- it's a freeby
