http://www.spottsperformance.com/Head%20kits everything you need for a quality head rebuild if you decide to go that route. Includes Crower springs suitable for that cam SC suggests! If you do have the heads off, a set of 1.72 Scorpion rockers would be a nice addition at this time. Spotts has good pricing on them too. (BTW American made not repackaged, with lifetime warranty too, about same price as Harland Sharps but better pieces IMO)
