Suggestions for knock sensor location?

My guess is that if there is going to be detonation it will be at the top of the stroke and make the piston rattle against the cylinder wall. My 1992 small block chevy has the knock sensor screwed into a water drain hole, but on the slant the water drain hole is next to the camshaft.

I recall GM has put them under intake manifolds since the 90s.

Thanks guys. The guy I bought my Haltech ECU can do all the tuning. He does this full time. His recommendation was right below the head in the middle of the blick. I think I found a web inside of the block that is wide enough and thick enough to drill and tap for a small bolt.

That looks awfully close to the exhaust...it won't get too hot?
