I remember the very first set of B1's I ever held in my hands....on the bench was an old set of iron 67' 915 heads that had Lord-knows how many hours of hand porting done to them.

I looked from one head and back to the other....It was hard to fathom how many years we raced the Iron heads...and then this masterpiece that absolutely DWARFED the stock head not only in flow but in sheer SIZE. Now we're talking!

I've built an wrenched on several B1's over the years but never had my own set....a 572" B1 megablock has a nice ring to it, tuned for the street though....basically take a 470" 7800 rpm race powerband and compress it into an "all in by 6500" street motor. another 'one step beyond my 517.

I'd like to find a black 70 Road Runner (personal fave) to drop it into, dog dishes...bench seat.
