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.

You happen to have a way to check the deck height? That will be how high the piston is in relation to the top of the cylinder. Figure out how to get that measurement and call whomever you want to order your domes from with that info. They will also wanna know your fuel's Motor octane number (Mon) as well as the temp and elevation you posted.

 

If you just have stock crank and jugs you can probably skip the deck height part if you are SURE that there has been no machining on the top or bottom of the cylinders.

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 :)
