Engine Builders-KB356 Piston Milling

I appreciate all the replies! Not the news I was wanting to hear but would rather know exactly what I am dealing with. Looks like a conservative tune, 160* thermostat, some 93 and some octane boost each fill up will be what my formula is. Will try and find a thicker head gasket but at the same time I am opening up my quench area in doing so. I think short of ordering a custom cometic, or opening up the chambers on my cylinder heads I dont have many options.


The 160 degree thermostat is a BIG deal. You don’t have near enough cylinder head to warrant a 114 LSA. I’d leave the compression where it and use a different cam. Don’t know what you have for gear or converter but both of those affect the CR you can use.
