Default Flycut exhaust side?

After measuring...how many of you had to flycut the exhaust? I was just told that I won't need to.

The setup will consist of:
243 heads milled to 62cc's
2.02 intake valve/1.57 exhaust valve
231.4/235.4 .617/601 111.8 LSA +2
.045 gasket

...thoughts? (on the overall setup or the flycutting)

Thanks!

I was right within tolerance with a TR224 and 63 cc's so I'll probably have to flycut the intake. I just didn't know it was that rare for someone to need to flycut the exhaust.

What is your setup JPH and what were your intake and exhaust measurements? Thanks!

When I've done it in the past, I do both, why, so I do not have to do it again if I ever went bigger, or different LSA/ICL, or retard.

Agreed, Its only a few more CC's out of the setup. While you are there, It would be alot easier to go ahead and fly cut both sides. You will more than likely thank your self down the road.

Before you flycut, do you guys remember about what the exhaust measurement came out to be? Thanks!
