i looked at a northstar engine in a friends caddy the other day. the plugs appear to be mounted in the center of the valve covers like the hemi's is this a hemi head engine? the car was very peppy 300hp rating.
No it's not a hemi, it's a 4 valve per cylinder head like the FoRd Cobra, Honda 4 banger and the discontinued Corvette ZR1 LT5 engine. I guess you would call it a double wedge head.
