Head and cam selection help for 440

TF 240 for all out power build.

I wouldn’t consider the TF to be the “best” std port head for an all out build.
Not as they come ootb anyway.

The std port Victor can be ported to flow more, and so can the std port EZ....... but to get there, you’ll have more $$$ into them than the TF heads ootb.
The TF heads can be ported more as well........ but I have no data from my bench to coincide with the time it take to see worthwhile gains, and the costs involved with going that route, and what kinds of improvements can be had(while retaining the std port opening).

Probably the best std port head, as it came ootb, was the 260cc Chapman Stage 6.

Edit: I haven’t done any in several years, but Indy SR’s can also be ported to get into the 340cfm+ range while still retaining the std port opening.
It’s fairly labor intensive, but overall probably not any harder than getting there with the 2nd gen std port Victors.
