[330CubeGt]

Just an update...
I bought a set of GT40P heads which have been recently gone through completely with a 3 angle valve job. Ready to bolt on.. Just curious if I should upgrade the springs ? eventually I would like to go to a mild cam upgrade.. Thanx, Tom

Much easier to do the springs off the car and if you plan on going with any aftermarket cam i would recommend putting a nice set of springs on the heads it will save you the hassel of doing it on the car later.
