I use Champion RS10YC or RS12YC. Anything from a RS12YC to a RS9YC will work fine. I get years out of these plugs in my vortec motors.

Yes.... For a performance application use the RS12YC or RS10YC plugs.
Don't worry, these are the right plugs for your vortec headed motor.

im using the rs12yc plugs and i keep fouling them. this is 2 sets now, should i go with a rs14yc? or the rs14yc6? i took one plug that was firing and checked each individual plug wire, so that elimenates it being anywhere else in the ign.. the fuel pressure is at 6psi exact also. is there anything im missing here?

Something other than the plug heat range is causing the fouling.
You are overlooking something else liley in the igntion system (coil cap rotor etc)
These plugs are barely cooler than a stock plug and will not foul unless something is really rally really wrong (A stock plug will foul too). Don;t overlook new parts just cause they are new.
Check the actual supply voltage feeding the HEI distributor or spark box.
with a volt meter, must be 12V+.
if you are using a HEi remove the coil and inspect the high voltage center post under tha coil in the cap. If you are using a aftemarket coil and or a aftermarket spark module and or a CD ignition the stock carbon center post must be replaced with a high perf steel low resistance center post or it will melt and you will get severe spark scatter cap and rotor burning and fouled plugs. Check the pick up coil with a ohm meter. move the vacuum advance around to see if the resistance fluculates (intermident faulty mag pick up coil wires) make sure you have a good electrical ground strap running from the engine block to the steel fire wall of the car. (Commonly overlooked ignition fault)

you ahve a severe ignition fault that has nothng to do with the spark plug heat range.

i have found out that im still getting too much fuel. i have the edelbrock performer fuel pump with 6psi. could it be that there is too much volume? even though the use of this POS is recommended with edelbrock carbs? i have had 2 oem pumps 1 with 15 plus psi and the other with 7.5. i dont think it is in my ign. there is so much fuel it pours out the headers. i have took the carb off and put it on another car and it does fine.
