its all stock. all thats happend is a .040 borr and vitos superstock. the alkylat is 95oct 4%etanol and i can buy it pretty cheap, sometimes for free . otherwise i can buy 98oct 0%etanol. it dubbels the price and i dont know if its worth it. As it is now im the fastes

Im having a service and thinking to by a new head. And i need a little help with domes. I drive on alkylat and i belive its 2%blend, Do i need to put it all back and check my comp and then order new domes or can I do it some other way before I buy? right now its 30c and 0-300feet above sea.
