I just can only say again,,,you cannot use a 1.94" intake valve in a 194 head,they cannot flow that way,(unless you modify the chamber greatly) you would need to cut down a 1.94" intake to a smaller size to make it work & be a closer/better comparision.
Valve jobbing is very critical,if one seat is .010 wider on one cylinder head, another head being compared to has a narrower seat, you can loose 10-20 cfm just from that alone.It depends on a lot of factors.
Like I said before,you dont learn this stuff overnight,just in a couple hrs is all it takes, sarcasium, again, sorry.
