Does anyone on here know the measurement is be looking for on a CPR piped viper. Looking for 500-600 ft drag sled. Heads will be modded after I finish this last part. So... Anyone looking to share some knowledge with exhaust port height, stock is around 32mm, I've read where others have ran 30.5 mm. Anyone looking to shed some light on this?

I,ve got two Simons cylinders here on the shelf. One is numbered 6218 and the other is 6217. Both measure 1.232 and converts to 31.292. I think you are setting up perfect 30.5 is .012 thousands shorter than these two.
