if i get these wont it affect port timing? and if it did what kind of power would it be? and would it be safe to run with 0=4 timing, and pump gas (93) and the mods in my sig?
Isn't that just a thinner head gasket. I wouldn't use their base gasket. the oem one is the only base gasket i trust. you should be fine with the mods you have it will just up the compression alittle. not enough to worry about your gas.
agreed you should see the high compresion vitos base gasket i got didnt even look like it tryed to seal the only thing im ever buying vitos againb is a stroker crank and then its going to ken
