Valve Tip/Rocker Height Question??

No high revving for me.... 5800 and below. I do remember the machinist saying that he properly shimmed all the valves and had to cut the spring seats for the seals. He even told me the spring pressures but I don't remember what they were. But since I didn't know about the spring heights I didn't even ask. So your saying that IF the valve tips are not all the same height I could put the adjustable rockers on the heads and compensate for any difference in valve height?? If that's the case then it really doesn't matter that much about the valve tip height unless your using non adjustable rockers?? When I do the 390 I was planning on using 360 heads but on these heads I do plan on letting the machinist know about the valve tip heights even though it shouldn't make a difference with the adjustable rockers.


thanks,
