Who makes the best flowing heads for 4.030 bore and a THICK deck......for my 390ci...
So I'm looking for heads with a thick deck and the best flow I can get.......NOT 6 bolt heads. Just 4 bolt heads.
390ci.......I want the heads for when I do the Modular Turbo TT kit.
20psi is the plan.
Thanks.

Guys have made 1000+ with 317s, but I see where you're coming from. Look into the Mast Small Bore LS3 Heads, a set of 4.00" Bore AllPro -1 Heads, or have Chris Frank or RFD do some LSX-LS3 Castings for you. But seriously, there is no need for a high dollar head for your goals. IMHO it would be a waste of money on a 4-Bolt setup.

I went with the TFS LS 220 "As cast" heads. .750 deck thickness.
TFS-3061T002
$1800.
Been told I should be good for around 1300-1400 flywheel with the ls9 gaskets and 1/2" studs. Pending tune of course... Most of it is in the tune.

i agree with dude above. no need for those 6 bolts on a 4 bolt setup. but for future purposes and people like me who don't know when enough is enough and want to make 1300-1400 on a DD a 6 bolt block may be necessary for the longhaul and you will def be glad you already have the heads for it to make the hit less brutal. $0.02
