<VV> #4 misfire, exhaust 'spit'

[Mike Ioanes]

. Oh yeah, the #4 spark plug did not appear like it was firing (others are a 
bit sooty, this one is too clean) when I pulled it. Compression is 150 +.

I would suspect a head gasket more if the compression was lower.  Aleaking 
head gasket does make a noticeable and distinctive "spit"...don't ask me how 
I know this, but it's the same reason I know that the right head will come 
off a 64 without taking the engine out of the car.
