1995 GMC K2500 Sierra SL 5.7L Cylinder Heads
Posted to GM Engine on 10/22/2000

I have the heads off for a guide problem and would like to add some cheap Hp/torq by shaving heads, putting in a thinner head gasket or installing some 305 heads. Has anyone done this with success and without adverse effects ie spark knock? I'm not interested ...
