I think he meant he also threw in LS pistons... not to mention who ever told you a GSR head on any B Series block would lower compression is a complete retard.hey bro i had the same problem, i had a gsr in my ek coup i was red lining 3rd and missed 4th & hit 2nd i then herd a loud knocking nois i pulled my engen apart & found a spun rod bering it was so bad that even my crank was no good so i used a b16 block and put ls piston head cus i was told gsr head on b16 block would lower compression so i lowerd it even more 8:5 it still felt pretty fast on top end i drove it for about 3 months till i got my gerrit turbo 15lbs of boost like nutin it wasnt that much eather like 2500 labor & turbo set up
