Valve stem seal & height info needed
Hello-
I am hoping someone might have an evo head off & apart, who can measure a few items for me.
The outside diameter of the valve stem seal.
The distance from the top of the valve stem seal to the floor of the spring seat.
I need this info to find out if I can install these without removing the valve stem seals.
I have just found a contact who can get ferrea manufactored parts, i.e. springs, ti retainers & spring seats @ a screaming deal.
These springs installed @ 1.5", they measure 80 lbs of seat pressure, @ 11mm of lift they measure 220 lbs. The valve spring can compress another ~4 mm before coil bind.
Thanks in advance
