92 oil leak

I got a 92 se twin cam dual v6 and today I noticed a good amount of oil on my garage floor I thought it was the oil pan gasket but it wasnt so I checked the heads and noticed on the rear head on the drivers side towards the top of the head there is oil trickling out I think its between the head and block but arent sure theres no antifreeze in oil I got good oil pressure and it dont smell like burning oil yet any ideas what I should check or do please help me I dont feel like taking it to a shop aI really dont know the history on the car as far as gaskets being replased or whatever:banghead:
