Nice seeing vintage Chrysler technology !!!!
Just this week I obtained a set of Bob Mullen Direct Connection race LA heads and they are beautiful and will heading to cyl head specialist in N.GA
Flow numbers soon.
Pics of Mullen head and development are all over the Larry Sheib book.
A friend had set done by Mullen’s place on a 70 T/A with T/A heads of course. He restored it to stock. So with stock exhaust manifolds, stock crank, and XE268 cam. In reality too much head for that combo. I’m sure that book brought in business to Mullen.
