yes 200 on the exhaust 300 on the intake. stages on the heads reflect the amount of work..to each his own.

If you really want to argue though, the term "stage #" is used by many to define the level of work done to the heads, so in a way we can say it's a "standard" although as mentioned above I never used it. A stage 2 head will out perform a stage 1 head and a stage 3 head will out perform both. Although there is no clear industrial defenition set per stage, we all know the higher the number the better the flow.

Not sure where you getting that I gave a "standard" definition for porting. Actually I don't see anywhere in my posts where I used the term "standard". In big boy land we know how to read.

Interesting... an unknown head porter's 3.5 job, by definition... because it's a bigger number... outperforms a Lloyd Elliott Stage 3.... because it's a smaller number. And then we can use that relationship to determine by extrapolation that the unknown porter's heads must flow 300/200 because Lloyd's only flow 280/195.
OK.
OK.
