thats an expensive head. but after speaking to some proper engineers, im not supprised. the man hours going into it i suppose.£750 is my limit. then some arp bolts while im there.may as well

how much would be gained ess_three, from bottom end work? based around, say, a eurospec crank? would it make the engine spin up much quicker?
without going into fored induction. itb's, tb's or carbs. what can be the absolute DRIVABLE power limit from an abf? is it the tb and inlet that restrict?
say, a fully blended head, in/ex tract. 260-268 cams. stanalone management, and a lightened/worked bottom end to handle the extra revs?
mike_h had a 2.1 hotgolf abf bottom end for sale which i missed out on. shame
