I am in a bit of a pickel now b/c my valvetrain geometry kit uses the current 2.02" valve size and going to a bigger valve now would negate the fit of that kit. No it wont

I will look around to see if I can find the same length valve though, but not likely...LOL Econo heads, are you using 5.240? Not exactly a rare valve length. Ferra should have them

In the meantime, the current flow bench guy who suggested that I should really do a valve job says the following:
- 4 angle job
- blend in to a 3 angle after
- do a backcut on the intake valves

So that'll be the plan for now. I'll update with the new flow results as we finish that work.

See above in Red

If your valve job is effective, you'll be looking at 320cfm so a 2.08 would be beneficial.
