I'm building up a 3.8 to drop into my 87 firebird. I know that the tta's came with different heads than the tr's. I've heard fwd 3.8 heads?
Question is should I stick with the 8445 heads that I have, or should I switch to the fwd heads. What would the benefits to a fwd head be? There must have been a reason that gm made the switch.
