We buy our Edelbrock heads bare so that we can install the parts that we feel are best suited for the application. The springs, retainers and locks that come on the Edelbrock heads leave a little to be desired. You can also install larger valves if you want to this way. Depending on the bore size you can run a 2.150 intake and a 1.72 exhaust valve. We also do a special valve job and back cut on the valves that picks these heads up about 20 to 25 cfm on the intake at .500 and .600 lift with out hurting the low flow. We sell a assembled pair of heads with all of our parts and valve job work for 1495.00. These include 10 degree retrainers and locks, dual springs, spring cups and seals. We supply a parts list, assemble heights and spring pressure set p for your application. You can also go the CNC stage 2 heads for only 2195.00 and these will support 600HP. Good luck, Keith Craft
