How much variation are you seeing in flow and port volume from port to port on these heads? How about variation in chamber volume from chamber to chamber?
We did a compression test and had 5 cylinders at 175lbs., 2 at 180lbs. and 1 at 185lbs. so not bad for untouched chambers.
I've seen +/- 2cc so far.
Ports seem to flow within 1% of each other but I don't test each port unless I'm paid to which is almost never! I do use templates alot when I port to help keep things equal, but these heads only got the valve job blended.
