I am getting my head all dialed in and lapped my valves that look outstanding considering they have 157k miles on them...no cracks and everything is coming together nicely. Before I throw in the 7A cams into my 3b head, do I need to swap in anything different as far as valve springs go? The 3b ones are all within tolerance and showing great but now is the time before I throw the valves back in...my goals is 400whp max on a gt3071...I will have coil on plug as well...still figuring the tuning out. Regardless, any help on the head valve springs would be greatly appreciated!
