Well, i tore into my engine the other day, some of the center head bolts were
slightly loose, but #7 was the one that was getting water into it. When I
pulled the head, the fel-pro 1010 gasket fire ring had pulled away from the
material and into the bore on #7, and the #1 looked the same way. I took it
to a trusted engine builder, he took one look and said detonation. I asked
him if I really needed to retorque and he said not with modern gaskets, just
racers using copper. That's a good thing as I am using roller rockers that
are too wide to allow access to the head bolts without taking them off. He
did sell me some felpro 1003 gaskets for way too much. He said 40-55-70 was
the torque sequence. I got home and took the other head off and the gasket
looked just as bad as the other one, although the bolts were all still tight.
And nothing was leaking - yet. I took everything apart, cleaned it all up,
checked for any grooving in the heads, and put it together. I suppose I will
set my valves and reassemble today.
I am going to take edelbrock's advice and re-burn the chip with the factory
timing and run 8 deg initial. This is less than I was running and much less
than the howell chip had before I started messing around. I drove about
10,000 miles on a chip with 36 total and more at cruise. So I guess you can
all learn now - you can have detonation without knock. Knock is reeeelly bad
detonation. And I'm pretty sure you don't want to experiment with using
cheap gas and burning a chip for same. I think that's what did me in more
than anything.
Thanks for listening to my electroyappin!
