Am I reading the guide correct? It says .....same runner, chamber, and valve size as head it is replacing

So a 61607 that comes with 2.05/1.6, 190/90 can be made into 2.19/1.71, 244/137 ?

Or can I be somewhere in between? the rule book says +.005/-.015 on the valve sizes.

S/S 351C I am confused ...can somebody help me out
