Indy LAX or J-heads?

Whats your opinion for a future build? im still weighing my options for where to go with whatever junk gets left when im done selling of things and what i can afford to buy at that point.
1 rebuild a set of very beat up J-heads that has 2.02intake valves that has a fair portjob done to them in the past (they ran high 11s in a 3300lb duster on a 340 with very worn bores) they have more than a few isues,a few valveseats are sunk bad enough that its clearly visible by just looking at the top of the valves.has a couple boltholes that has been redrilled and threaded in different sizes ,some of you probably know the drill of old racejunk.
or
2 buy a set of Indy LAX heads with 2.02 intake valves and more or less bolt them on out of the boxafter setting them up for the cam i have

340 about 10.5:1 compression
XR280R cam little baby solid roller 242 and 248 degrees at.050 lift and .570/.576 lift
3500RPM converter.
1 7/8" TTI headers.
3.91 gears
Whatever intake i end up with.
750 proform DP or 800 EdelbrockAVS
73Duster fun summer car for nice days and the occasional track visit.
I guess i may swap the gears for 4.10:1 or so and converter for a 4-4500rpm unit at some point in the future to better match this if this is the direction i end up going but nothing set in stone yet.
Yeah i know this thing is far from a well matched combination,its just going to end up being whatever it becomes when im done and whatever parts i end up having but i want some kind of bang for the buck here,and not sure if there is a point in saving those heads in this case thats why i ask.
