Doh!


I have my 1st (well second really) Hydro head siting here on a
cardboard box on the floor awaiting me to finish tapping in new
threads- so other than removing it from the donor, minus cam, I
haven't taken it apart at all. Not only am I an 8v kinda guy, I have
traditionally been a mech. lifter dude too.


So, can longer/higher duration cams be used in hydro heads? [I think
so].

What are the ramifications on the stock springs then?
