missing after a hard run

[88fivepointoh]

well i have managed to smoke a new corvette since i got my problems resolved but the only thing I have now is after last nite I raced a 300zx and smoked his @ss hard it seems to have developed a hesitation and miss. I drove my car around tonight for a while and it seems to mostly clear up after i did alittle driving. could my plugs be at fault? I am using AC delco rapid fire #1's.. I like the electrodes on them. they are similar in design of the denso irridiums. Could I have heated them up a bit and glazed them? My engine temp did go up about 2 lines from normal after I ran it hard.
