Small Block & Big Block Chevy Specific - stock 64chamber heads, want to upgrade!

hey whats up? i was doin some research and i found out that the heads that i have now are 10110810, those heads have a chamber of either 64 or 65 vavles 1.94 1.5 , and from the little information that ive found on these heads they make some good low end power/torque but they suck @ anything above 4k, right now i have the tpi system so i guess that evens out since tpi system stop makin power ~5k!! i will be gettin the lt1 manifold and right after that i will be upgrading heads! which ones should i go w/??

heres my setup: 350, stock bore, flat top pistons,roller cam .488/.495 264/269, 1.6 self-adjusting rocker arms, 52mm TB, airfoil, 255lhp walbro, afpr, msd ignition coil, msd dizzy cap/rotor, 160degree stat, shorty headers, 3200 stall converte!

which heads would you recommend, i'm not tryin to spend a fortune on the heads and i dont plan on going with anything higher than 93 octane!
thanks in advance!

Pretty mild setup, i say you could go with soe RHS or Patriot heads, 170cc intake runner, unless you are going to go bigger on the cam size later, use a 1.94/1.50 valve set. You can allways upgrade later.

I am planning on the patriot heads early next year, I'm broke right now though.

i have not yet ran the car but my goals are mid to low 12, if i got the lt1 manifold and left the heads as they are now (mildly ported) but changed my gears to some 3.42 and some suspension work do you think i would see that big of a diff.?
