which SBC head?

DRR Trophy

Know everyone has preferred brand... tell me why you suggest what, for my specific combo please.

Want to stay with standard head please. Nothing exotic. Budget build with everything I do.

Want to step up my bracket combo just a little. Currently have Dart Iron Eagle SBC 434 ci. OLD set of Track 1's, stock. 12.5 to 1, .630 lift roller cam. On Alky- Rupert carb.
This cam stops at 7400, but I am not turning it that hard. Leaving at 3500 - glide w brake, 5500 stall, shift 6800. Mostly 1/8th mile.
3400 lb Firebird, 4.88's 28x9 MT PBR slicks. 1.46-1.48 60' time, 6.70-80 in TX summer heat.
This combo was good to me this year, just won Track Championship at TX Motorplex in NoE. But we always want to tweak...!

Thinking mid size runner volume (210 range?), but with alky, not sure of impact.

Again, give me some facts and whys please!

Thanks
Ken

What is your goal. Chad speier racing heads has a pretty bad 23 degree head available now. I imagine it requires shaft rockers. If you don't want to go that far...why bother. You will spend many thousands regardless of what head you invest in. Why take a tiny step? I am going 7.90 with ported track 1s in a 1775 lb dragster.

My old track 1's were just available when I was putting this motor together in the spring, $ and time said get it done with what you have. They are tired.
They had a couple of ports with some dings from previous owner, need surfaced, etc. I just lapped the valves and put new springs on it, made do with what I had.
Now I want to speed it up a little over the winter, 6.40-6.50. Might play with cam timing some too, but have to be easy with the 9" slicks.
Really want to keep it consistent! That is more important that going faster.
Interested in what volume I need for the alky carb, especially below 7500 rpm.

thanks
Ken

x2 on the afr 220 just replaced some old track 1 with a set. Anything better than that head is most likely 60/40 valve spacing and would probably need pistons.

are you running flattop or dome, dart makes an iron head with 49cc chamber 230 runner that would be good on alky and make compression better flame travel but with flat tops. The alky will help cool the steel heads and be cheaper than other alum ones

Haven't compared to anything else, but I think my flat top 383 with old AFR 220's runs pretty good for what it is. Best of 6.33 @ 108 normally 6.40's at 105ish in 3200 lb back half Camaro.

If I were going to buy a new set, AFR 220's would be my choice.

I'd be interested in the old, worn out Track 1 heads when you're ready to get rid of them.

I do not know how much if any the AFR 220 heads are than the Track 1 heads. Now the AFR 245 would be a good step up.

Ken, I would call Lloyd Elliot porting and see what he says. He is in Red Oak and is pretty helpful.

Over this past winter I upgraded from a set of Tracks 1's to the AFR 220 on a 383 like mentioned above and picked up alittle over a tenth in the 1/8 and 2 mph. Took them out of the box from summit cleaned them, put a shim under valve spring for alittle more pressure and bolted them on and have been badass ever since. you will need to get new stud gurdles but other than that I am a big fan of AFR on the sbc!!

Go with the 245 AFR's the 220's are to tight in the push rod pinch area and seem to run out of air on a 421 around 6300 RPM but make Killer torque.

I'm just thinking about time picked up vs dollars spent. Instead of buying new heads complete, they could be ported much cheaper and easily exceed the AFR number. My track times tell that I am between 725 and 750 hp with my ported (extensively) Track 1's. So there is more meat on that bone than how they fall out of the box. I just hate to see someone spend time and money on a set of new heads to maybe pick up a tenth.

Chad, can you post a few more specifics like B+S, CR, head / intake and fuel system with the dyno sheet of this build.

Like another has posted, this op should be contacting you.

If you were able to remove 200 lbs from the car, it might be close to the same et improvement as replacing the heads in the 1/8 mile… just saying.
