Which one is which? also the S3707 shows to be adjustable on the summit racing site. I am looking for direct bolt on no more parts needed.

call 'em up and ask them.... (and cross your fingers for someone knowledgeable)... you need the S70037... I'm thinking the other ones are the same thing less the pedestals, but that is a fair amount of supposition on my part..

One is adjustable, the other is not, the ones that bolt straight to our engines without additional work are the non-adjustables.

Been doing some reading on this mod since I'm wanting to do it soon. Couple people out there suggest doing the springs as well since they have been compresed at 1.6. It was thought there might be some valve float if not. I just sent for the HS catalog and asked them what they suggested. You guys have any thoughts on this??
