Octane question.... I got a nice 2T Race 72BBK kit from Carlos(autotech355) Head is flat..I mean FLAT! Only dish in it is where the spark plug hole is. About a .5mm or less squish band....so it knocks really bad. Here in Michigan we have no dedicated high octane pumps...so when I get gas 1/2 tank is the 87 from the car before me..which is still in the gas pump system...the rest is 
octane. I added a head gasket..still knocks. Put on a total of 3 head gaskets...no more knock...but no more power either. 32mph tops...and it used to hit 50-55 easy.It just knocked and ran hot then. Soo bottom line I am sick of the knock that is surely going to eat this expensive BBK. Extra head gaskets are not the answer.Soo..has anybody had any luck with the Octane additives. Yes I am wise enough to know they do not give you extra power as many think higher Octane does. I merely need the knock to go away. yeah I know...should have bought a Sport or Street kit..but for a few bux more I figured..? Had no clue I would run into this.Odd part is at first it seemed ok...but now you can see by a plug chop...there is detonation. 
I made sure when I removed the head to clear nay carbon buildup. Which was little to none!Top of the piston was a white/grey color 
Bottom line..will an Octane booster help? Do they really work even? Which I am skeptical of as many fuel additives are falsely advertised garbage. umm...help??? ;D
