Stock rollers/aftermarket cam

Spiders....you mean the link bar things and the steel ratainer plate that bolts into the lifter valley? If so yeah, that will work with anything as far as I know. I cant see why it wouldnt. ANd you have to use it. It holds the link bars on the lifters. Without it a lifter could turn and you could have A BAD DAY!

The beehive springs Brian supplies with the RHS head are more than fine for the factory Hydraulic roller lifter.
