You would have to know the valve spring assemble heights and the actual spring pressures as well as the spring part number. There are BeeHive springs that Comp has that the Tech line does not even know about. I would not talk to these guys anyway about any of this because there is to much that they do not know. Talk to an engine builder, the guy that built it would be a good place to start.
I have used some BeeHive valve springs that the Cup guys were using that the Tech guys probably do not even know about that set up at like 1.950 or 2.000. I would have to go back and look but did not coil bind till .750 lift. They gave me about 150 seat and 400 open. I was running on an hydraulic roller to see if I could get more rpms out of it and it help about 300rpms because of the spring being lighter as well as the titanium small retainer is lighter. Install titanium valves and you can get another 600 to 700 rpms.
I guess my point is watch who you talk to at any of these tach guys at any of the cam companys. They told one of my customers that he had way to much spring pressure because all my customer told them was the part number on his spring. They have an advertised assembled height of 1.950 listed for this spring but they did not know that I had it set up at 2.050 which made the pressure a lot less. The bottem line is get your assembled heights and go get your springs checked for pressure and coil bind. Good luck, Keith Craft
