Standard exhaust port BB heads

Thinking of changing 452 heads to something "better" on a 451. Better flow, same intake/exh port locations.
I don't want to change headers.
TFS 240, Edel RPM, maybe even B1BS ?
I'm not that knowledgible on the exhaust port locations.

Also Indy EZ cylinder heads.

NOT B1-BS; definitely raised exhaust port, although standard-height intake

Trick Flow 240 and Trick Flow 270 exhaust ports are very close to stock location but spark plugs are angled. Same with Indy EZ heads. 440 Source heads are same as stock with straight plugs. I think Edelbrock RPM is stock location and angled plugs but they might have a straight plug option also.

The current “default” std port head is the TF 240.

Best bang for the $$$.

Thank you Gents very much.
