In the '90s, I bought a set of the Batten aluminum W2s, 322 CFM @ .700 intake.
They soon after sold out to Indy, who I think turned them into the 360-1 & 360-2 heads after revamping the weird Batten valve guide/spring seat design..
Oddly to me, nobody talks about them; TrickFlow seems to be the top SB head nowadays.
Are they not building/shipping them ?
Looking at the ICH catalog, I'm confused by the differences between the -1 and -2.
