Thanks for the info, unfortunately I have no idea who makes the springs that are on my heads as I bought them complete, I do know he was going to run a .530 solid cam, there's a chance that my heads have already had some of this done as they have had various machine work done in the past, he just never got them ported as he was going to do the heads and intake at the same time, maybe I still have his number and I can find out more. THIS THREAD HAS BEEN VERY HELPFUL THUS FAR!!! THANKS FABO!!!!
