i've got a 454 with merlin heads. i put the car on the lift yesterday to change one of the spark plug wires since i have the 2 1/8 headers. on the drivers side at the rear corner where the head and block meet is wet. are chevys known for leaking there?

the motor isn't smoking and i can't smell coolant.

any chance it's not a blow head gasket and just needs to be re-torqued?

since i don't know squat about chevys. what's a good book for me to get? i would like to get a good performance book that will tell me bolt TQ order and how to adjust the rocker for a solid cam.

since i have to pull the steering box and the headers. i was going to get new coated headers to put on. since i have power steering i was thinking of getting the 2in hooker comp's untuned headers. i've got the 2 1/8 hooker super-comp's now that are tuned. is there much of a differance between the 2 inch tuned and untuned hooker headers?

thanks for you help.
