Heads for 440

If you go with the TF heads, it will be about 1 point of compression gained.

Totally Stock 452’s would be less of a head than the mildly reworked 906’s used for the EM comparo.
I can see where they would be 10-20hp less on a build like that.

The TF240 is arguably the “best” head you could put on your engine.
