I will prob order the block in a few weeks... If I wait that long. Ill call about them sending a set of 243s with it when I do. If it isnt much more then a few hundred Ill look into it. Ill do some research around Monroe to see if anyone can do good head work and not try to break the bank while doing it. Otherwise Ill prob just order the Patriot heads if I cant find a deal. I never expect something to perform "as advertised" But if it is worth 20 to 30 rwhp I can see use in it. Keep in mind Im still not looking to be the fastest... just faster.
