Has anyone any experience with SuperTech valve-train products? My current plan is to use VAC Performance valves, springs and retainers in my head rebuild. Though I came across supertech's valves which appear to be manufactured for better flow, which is intriguing but I'm always highly skeptical buying parts manufactured by companies I've personally heard little about.


Also being a firm believer in "You get what you pay for", the fact that the spring and retainer kit is $200 cheaper then VAC's kit makes me wonder. Valve Kit roughly $90 cheaper then VAC.
Any experience or thoughts on the matter are highly appreciated.
