will aluminum heads with larger combustion chambers really make more power than my gt40 port and polished heads? and are they really worth it in the long run i just bought a set and im having second thoughts on installing them

[Newb]

Either way you decide, shoot me a price I am in the market for a set

[mxnate116]

yes

[93hatch]

hope you didnt mean larger combustion chambers as that being a good thing for making powa

[1slow5.0]

well they are 64cc and i just spent 1400 on them with ferrea valves and spring and titanium retainers and if dont put them on i will take a loss lol but im sittin at around
12.5: cr right now and its hard to find gas that wont ping or detonate so i may lose a little power if i install them and thank you for your inputs and mxnate what did u mean by yes

[93hatch]

what heads are they? were they off of corral? tf 170s?

[mxnate116]

well if its a street car, then the trickflows or whatever they are will help big time. if your having to pretty much buy race gas its not worth it on the street. what are your GT40's flowing at now?

[1slow5.0]

they are real pro competition heads not the fake ebay shit lol and dont know what they flowing really and its my dd that gets 7-9 mpg but it dont make much power past about 45-4600 it flattens out i think its choked a little bit thats the reason i bought them but i dunno it runs so good now i dont realy wanna fuck with it ya know but i have to mix 115 with 93 or a gallon of toluene to drive it and its costly

[93hatch]

pro comp heads for 1400 eh

[mxnate116]

jesus fuck 7-9mpg? i can get 17mpg out of my car in city

but dont get pro comps, find a better head setup

[1slow5.0]

the valves and springs and having them polished costed quite a chunk they were about 700 bare so not as bad as it sounds lol this is my first 5.0 so dont know much about them i do know know ive wasted like 3 corvettes and shit tons of ricer honda lol its 306 stroker kb forged pistons crower h beam rods cosworth crank port and polished gt40 heads trickflow track heat intake bbk 70 mm throttle body and spacer bbk cai and 70mm c&l maf with 24lb injectors b303 cam tko tranny 373 gears and a spool in rear underdrive pullies and ac delete kit, olvers racing radiator elec. fan hi output waterpump 140 degree thermostat equal length headers 3" duals back to flowmaster 40s 16 cobra wheels and msd distributor and morroso 11mm plugwires and frpp 42c sparkplugs and thats alll i could think of that it has other than subframe connectors

[1slow5.0]

i bought them like a month ago suggested by a good friend but think i got bent over and ass fucked and the gas milage is terrible but there was time slips in the dash of 10.58 at 147.?? so i mean it runs like hell it breaks loose at sixty on freeway in third with 245/50/16's on it and i think it would get a lil better mileage with a fuel pressure reg and it has a 4hundred something lph fuel pump so its sqirting some gas lol

[93hatch]

306 stroker

[jessemachone]

what makes your 306 a stroker?

[1slow5.0]

technically not a stroker because stroke hasnt increased at all just .030 larger bore but thank you for catching that my mistake for using an incorrect term

[93hatch]

looks like a solid low 13s combo

[1slow5.0]

and it probably is now when i bought it it had a 175 shot bottle, solenoids lines and all that shit in the trunk so i sold it since i dont like like bottle feeding cars ive had bad experiences with it
