302 heads

powermaxx · Mar 3, 2006

what are the best heads for a 5.0? i heard the M-6049-X305 gt-40 heads are bolt on 65 hp. and they have 58cc chambers wich would make it 9:4:1 compression wich is what i was looking for. has anyone tried these heads? what are they like? what is the power band?

i would say get a afr 165 or 185 if you want the best.

what kind of hp do the afr 165s ahve out of the box? with the 58cc chambers
or should i get the 185s with the 58cc chambers?

what is the difference?

which are the best heads for a motor with a cam and intake?

which have the best bolt on hp and i want at least a 58cc chamber

also the heads dont have to meet emissions standards.

If you have a fairly stock 302 get the 165 heads. They will add at least 85 hp!!!! AFR rules!!!

AFR 165's...have to have pistons notched to accept afr185 if it is a stock shortblock

powermaxx · Mar 13, 2006

it is a stock short block

does any one have any hp results for the afr 165 heads?

290rwhp/340rwtq......edelbrock intake, trick flow cam, AFR 165 heads, BBK LT headers, etc etc. Approx 340-350 flywheel horsepower and 380-390 ft/lbs of torque.

powermaxx · Mar 13, 2006

wow those are good numbers
are they on the stock shortblock?

Jason 302 · Mar 13, 2006

No it has been bored +0.030", SRP pistons, stock rods, stock crank, balanced assembly.

Twisted Wedge's are the best head you can run on the stock pistons, which is why I bought them.

302RollinHard · Mar 13, 2006

Go with a name commensurate with Hot Rods......Holley or Edelbrock, you can't lose.

powermaxx · Mar 13, 2006

why are the twisted wedges better than the afr's?
everyware i see the afr's are the best.

bynummustang · Mar 13, 2006

Its all a matter of who you talk to. I have 351 Windsor heads, and I love them. But AFR are great heads and same with the Twisted Wedges, but AFR=$$$.

Trick flows TW or AFR 165's on a stock shortblock. cant go wrong with either.

powermaxx · Mar 14, 2006

has anyone tried the brodix heads?

what kind of price difference are the trick flows to the afr 165s?

i like the afr 165s cuz i wont have to get them milled since they come with 58cc chambers.

will i have to get new headers or can i just use the ones i already have?

powermaxx · Mar 18, 2006

how much are the afrs compared to the trickflows?

FastDriver · Mar 18, 2006

about 1000 vs. 1300 for the AFRs.

I agree, you can't go wrong with either. I prefer AFRs slightly despite the price difference. AFR 165s will accept stock headers.

I made 311 rwhp/ 330 rwtq with AFR165s/cobra intake/FTI cam/shorty headers. Then I had Ed Curtis Port the intake and put on long-tube headers. I'd guess it was probably making another 10 rwhp or so.

powermaxx · Mar 19, 2006

the trick flows wont accent headers?
or just factory ones?
i have dynomax longtubes will they work on a trick flow head?
