Single valve springs or double? Use stock type valve seals or positive style? Do these flow like x heads or better?

 

[Jeremy]

Single but there strong.
Have tight bronze valve guides and No seals. Can use stock type.
They'll flow as well on intakes mopar says better but flow much better on exhaust. Popular choice for Super Stickers because exhaust are so good.
