Trick Flow Heads
Has anyone installed the Trick Flow heads for the small bore 305? I have a 1983 TA with the 305 HO motor and was considering these. Would like to know if anyone is running them and what kind of performance gains they realized,

I haven't seen them run but your choices for small bore is slim. Holdener did a video on his tests

Seen a few builds. One or two guys on here had them on 305 or 334 strokers
richard holdener made some decent power with them, 612 with boost

That said, I think the TFS 175 heads are great heads for a 305. Helping a friend with a remote build and that's what he ended up going with.
