Which heads to buy?

Working my uncles 92 GT it has a 93 cobra block with, Ford racing crankshaft, E303 cam, 1.70 svo roller rockers, gt40 heads, edlebrock performer rpm intake manifold, 70 mm throttle body as well as the mass air flow, 24lb injectors along with a bbk fuel pressure regulator which is at 25lb's, also fuel pump is a 122, my uncle wants new heads since he wants more power and wants it nitrous ready, my question is which header should we go with, Ford racing turbo-swirl gt40x 58cc or 64cc or if there is another head someone would recommend!

The TFS street head or AFR 165 would be a great choice for your combo.The TFS head has 61cc chambers & the AFR head has 58cc chambers.I prefer the TFS head because you can run a cam with more lift on it vs the AFR head.Your e303 cam lift(.498")+1.7 rocker lift(.030")will give you a total of .528" lift.The TFS has bigger valves too.
2.02 intake 1.60 exhaust.

I've used TrickFlow since they first came out and are one of the best....maybe not out of the box best but with a little work they can be.
They do make a 56cc and 58cc chamber....just depends on what you are wanting out or this motor...just street....track/street....drag race/street/track...also depends on what headers you have now and what head gaskets you use....I'd also use head studs over bolts....they do give you better sealing....
You will be needing to run premium fuel in all cases...which I assume you are anyway.
Give them a call and discuss your needs and they will steer you into the right head....they have just a few years of experience...

Yeah you're absolutely right.
Like you said,it depends on which head you get.They sell them with the following combination of intake runner & combustion chamber size.

(Intake Runner) (Combustion Chamber)
**170cc** 58cc/61cc


**190cc** 56cc/66cc


**205cc** 56cc/66cc

If you're uncle is gonna be doing more street driving
vs strip,the 170's are definitely the better route to go.If he's gonna be racing the majority of the time,the 190's might work better on the top end & when the nitrous is on,but it might lose some torque down low since he's still running the stock 302 displacement.If he had a 331 or 347,the 190's would work better for sure.I know he'll be making more power once he hits the nitrous button,but thats only gonna happen a small percentage of the time so he needs a head thats gonna give him good velocity when the nitrous isn't on(which will be most of the time)

170s for a 302 bottom end. They'll flow plenty and have a ton of "meat" on them if you need them ported later. They can be hogged out pretty damn far or just sell them in a few years when upgrading and put the $$$ towards some bigger ones.

I had a 302 with TW heads and when I went the stroker route I had the heads ported and they flowed in the 290's and 220's. That was also not super aggressive as they said they could have gotten some more out of it.

Yeah lots of ppl who go to a stroker save some money getting their TW heads ported out vs selling and then paying $2200 or whatever it costs for the 205-225 cfm units. You just have to watch out which porter you use and make sure its not some fly by night shop.


That being said. The TW170s with the combo he has listed are not going to be a HUGE jump in power over what he has now. He might want to look at just tossing a 150 shot at it which will punch him up over 400hp by itself.


Or he should probably look into an Ed Curtis cam to install when he does the heads vs leaving the E cam in there.

Got a friend who just slapped a RPMII, TW heads and a custom cam on a stock lower end and laid down 320 to the rear tire in a gutted car. Runs really nice.

320 is about right for a properly done HCI 302.

Making 400hp at the crank is a pretty easy and mostly straight forward.
The three keys, cam, heads and intake...........since I'm not an ole school guy a 750cfm carb on a Parker with a cheap set of ProCom 205's and split duration roller cam in a junk yard 302 that is half way decent will give you 400hp. If you can get the motor on the cheap you'll spend less than the cost of the TrickFlow heads to make 400hp...............is it reliable.............just depends on how much attention you give the motor....IMHO

This is a good reference chart for SBF heads and what they flow.....just some food for thought.....yes, this is a number of years old but still gives a good indication of what they can do.
