I would return them just because of the fact that being dished stock replacements your compression ratio will likely be in the 7s. That cam isn't really big, but it would really like more compression for more low end response but it would work. It really depends on your gearing and torque converter. In my opinion under 8 to 1 compression isn't good no matter what cam you run.
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

I built the same motor. Stock block, 292/292 duration 484/484 lift. 230@.050. Headers, RPM airgap intake, I cleaned the heads up. Stock mopar ignition, holley fuel pump 4:30 gears and a 2600 stall converter. It runs well for what it is. I like the motor for what I built it for money wise.

i used the kb-107's in my 360.with stock unmilled heads you will be around 9.3-9.7cr. those pistons worked great.Pay attention to the ring gap assembly instructions. stock valves will be fine. some 3.91 gears would help too

port em as far as you dare (they are expendable stock heads)/have your shop add 2.02's & unshroud the combustion chambers/bowl hog the bowls. dulcich has some excellent SB porting articles which might be avail on the Mopar Muscle archives

Slow down and do more research before dropping your $$$ down. You don't want to go off "half cocked", then be very unhappy with the results and $$$ down the drain. No sense in 2.02 valves on the street usually. If it is usually running 4500 rpm or less, 1.88 valves will be fine. Save your money for elsewhere. Don't say what trans you are running. If automatic, you will be much better spending money on a better converter than on big valves. If you rush and throw something together half arsed, you will be wasting money and leaving performance on the table. Carefully, patiently, get a plan together, then you will be happy with the results.

KB107's, comp XE268, comp #901 springs and matching retainers, and leave the 1.88's unless your valves are severely sunk...if the heads need more than a valve job (if they need new guides or valves, etc), I'd buck up the extra $$ and buy these headsgranted, stock dished pistons, headers, and a comp XE262 will get you into the high 13's/low 14's and run fine on 87 octane.
