If I were looking for a std port head with more flow than the TF 240 for myself, I'd probably use some Indy SR's.
I like the Indy external top end oiling, the raised intake port/valley plate arrangement, and the ability to use non-offset rockers.

Without Herculean porting efforts, they can flow in the 340's at std port window size.
It requires full porting to get there, but nothing really crazy.

If the std port Victors didn't come with the bowls cast so ridiculously small, I think they might sell more of them.
I like the Indy valley plate arrangement better than the victor plate too.
