I'd probably shy away from the Brodix 18* clones, as from what I've seen they don't flow that much better than a good 23* head. I like the All-Pro 23* heads if one were limited to a 23* head, those are killer for flow numbers and port configuration, but they'd require a big small block to work well...
Pipe rack? LOL!!! Hey... I still have my SFI-20 stuff around if anyone has an open seat!!! Hint, hint!!! Yeah, the front end update is one of the things needed. Car was built new in '90 and I ran it from '91-95 and parked it then. Usually ran Super Comp and brackets with my little 341" motor in it....
