ProComp/Speedmaster aluminum heads

While I don’t advocate using any heads truly “ootb”........ depending on where you’re located and what the local machine shop situation is...... I wouldn’t argue too hard against running a premium head like the TF’s ootb.

The local builders I deal with always have the heads looked over.
The last several sets of AFR heads I’ve had through the shop were good to go ootb.
The one thing I haven’t loved with the ootb TF heads has been the guide clearance.
I’ve had a few here that were really on the snug side.
Though, the last set of 240’s I had here were fine.
