with the sort of dollars being mentioned here..
can someone confirm what it would actually cost to buy an RB26 head and bolt it to your rb25 bottom end?
then how much could you sell your RB25 head for?
wouldn't that be a better option?
you get a better flowing head (stock for stock), solid lifters, more aggressive cams (?).
the goodness of FFP and 6 throttles.
I guess if you already have a head with work done to it you'd bother with all this, but even still.. from a dollars point of view, wouldn't it be cheaper to go the rb26 head route?
