Doubles with a damper.
I only have an on the head tester and no rockers for them , so I have no idea what the pressure was , but they were plenty stiff.
But I am guessing that someone had a big roller in what ever combination it saw before I got to them.
I will have them checked for leaks / cracks and use them.
If the guides need to be replaced , I'll switch to an 11/32 stem SBC valve at + .100 length and save some $$.
That is based on the assumption that I am not going to trip over a sack of cash in the next couple weeks and do it the right way. laugh2
