Adding 2.02 intake to J heads

I don't know what I was thinking??? I have a set of 360 heads, 1980-85 596 heads. I plan to install 2.02 valves and had asked (earlier) if the hardened seat area would be completely removed when the machinist cuts the valve seat for the larger valve. But like some of you are saying the 2.02 is an intake valve and the intake seat doesn't require hardening. So as long as I stay with the stock exhaust valve size I'll be OK on the hardened seat issue. I'm building a 318 stroker (390 CI), no high RPM/revving. It will be a torque monster, since I have a 2004R overdrive already installed I won't need high RPMs to putt around the streets or on the highway. I do plan to port the heads so that the 390 can breath but nothing above 5800 RPM. As it is, If I did my math correctly at 5500 RPM and the 2004R overdrive I would be cruising close to 189 MPH with the 3:73 gears I currently have.
No need for a anything over 6K RPM.
