Valve Springs and Seals Info?

WOW

for those who come across this thread if you make it this far here is what I got regarding the replies here and some further follow up I did on my own for valve stem seals

confirm valve stem size
confirm type spring
the umbrella type seal does work, not suggested as the best unless some weird reason it is the only option
for the positive stop seals, confirm ID size needed
the viton seals seem to be the best all around choice
Teflon is a durable option, not as popular


To all, again, thanks for the replies
