Hello everyone,

I want experts to put some combination here for Max output as N/A and Forced.
like which generation block (1UZ gens or 2UZ or 3 UZ) with which head (VVTi/Non-VVTi).
I thank you all for seeing and replying.

forced all heads you forced the air trough it.
to optimum head for forced air, is custom made. But it takes years to defelopment.

Na, dont know, but custom heads wins over stock 9 out of the 10 times, bigger ports etc etc
