Guys I have a 5.4 eaton factory lightning in a project car SOHC Heads.

I see trickflow has bad azz numbers, BUT !

5.4 DOHC HEADS OUTFLOW trickflow's new SOHC Heads by a LONG SHOT! EVEN PORTED TRICKFLOW HEADS OR PORTED PI HEADS.

My question is, does this mean if I do this messy DOHC conversion, will this
GIVE ME MORE POWER than if I just bought a set of trick flow heads ?

I Figure upgrading to one of these heads will blow my mind away! And need advice asap.

 

Are you staying/going supercharged?
For the amount of work involved, I'd go DOHC.
Check with Sean Hyland as he's been doing crazy schit with DOHC on both 5.4 and 4.6 mills.
