NOOO!!! Blew head gasket!!!!!!

I went to the track saturday to run for what would have been the last time anyway.....and yeah shit got bad. Two runs, 16.43, 16.51 and then on the third go all kinds of smoke and steam came spewing from under the hood. I was a very very angry man at that point as everyone there watched me roll slowly to a hault. Luckily a buddy of mine had his car there which he always brings on trailer so I was able to get it back home ok. Tore it all apart and know that I at least have a busted head gasket. I'm not sure where/why/how but for some reason a bunch of oil os missing as I get none at all on the dipstick. So I have no idea whats goin on there but I know it's probably not good. I am not an engine guru so im gonna take it to my mechanic tomorrow and see what he can find. On the other hand I veiw this as a prime opportunity and great excuse to rebuild my engine but I'm gonna need the truck for winter so I think I'm just gonna patch it up with w/e needs replaced for now and start buying parts for a spring time rebuild.
