Well, the rockers were just to compliment the rest of the upgrades....
The head swap was done to facilitate the cam....the rest of the changes were to make it all work together.....like it's s'posed to. The nasty cam and longer valves to facilitate more lift required longer pushrods to get the geometry correct. Pieces of a puzzle....LOL I did my homework and STILL had to buy more parts to make everything work right.
