Updating the engine in my streetcar. Looking at a new cam and top end combo. What heads are guys using today ? I took off some Track 1 heads. Shooting for 700 hp. Was probably in the 550-575 range before. Any input is appreciated.
AFR still is the go to head for street/strip small blocks. IMO, the AFR 220 Eliminator is what you want.

Just got this from Kirk, nice little pump gas 414 Dart sportsman block, Callies Magnum, Callies Ultra rods. If those Track 1's you took off are 215's, you could send em to Weingartner. I sold my old top end (215's) to a guy. He sent the heads to Weingartner and they flowed as well as my 233 sts Brodix T1's when he got em back.
This 414 we're doing is looking like 625-650hp with an old set of Dart 220's got a deal on shaft rockers complete in new condition.
This will be an engine we can put quite a bit of street miles on 66 Chevy II 200hp nitrous
Supposedly this is a "nasty sounding roller camshaft"

Ed, the AFR 220 Eliminator heads would be better than say, the 345 AFR heads ?

We tried to buy the Weingartner ported heads back with no luck but this is the new Wilson / Profiler intake we cut the fuel injection bosses off, gonna cut the plenum down and port for a 2" cowl 66 Chevy II.
I'd send them Brodix heads to Weingartner if I was you, that deal went smooth and they looked great. All new everything affordable quality. I was impressed, everything went down as he said it would.
MarkeMark runs well with Weingartner Brodix heads and intake too. Check with him too.

700 hp, pump gas 406. A cylinder head, camshaft rotating assembly with the latten potential for power around 8,000 rpm.
You could drive it on the street, if the valve train compromises are approached thoughtfully, replacing valve springs might not be every other time out chore.

Ever think about a small Procharger, wouldn't take much boost to get 700 hp. It would be very street friendly, especially with cam specs for a supercharger.

AFR dominance ended when I bolted this 427 together topped off with a set of out of the box Brodix T1 233 STS.

700 HP on pump gas with a 406 is not going to be easy with those heads. I would look at the AFR 245 or some 18* heads and or more cubic inches. I think AFR are very good heads but many say they are "Optimistic" on their flow ratings.
If you want to private message me I will tell you about some of my combinations and actual dyno numbers. Not going to get into public pi$$ing contest here with internet hero /Zeroes.
With pump gas cam selection and compression will be critical to.

You're arguing with yourself, only because there is no AFR 245 dipping in the 5's n/a sbc factory condition all steel 3200 lbs.

I did the engine and transmission. I told everyone I'd go a 5 before it saw the track.
My dyno is better than most, it'll tell me what i'm gonna run beforehand.

I'd send the heads he has to Weingartner. I'd get a stick around 730 670 270 280 106, and have PKRE do up a SV2 intake like this for it. It'll be real close 700 hp. He can drive it a little car shows hamburger joints Saturday night.

your nothing special race engine is not a 700HP pump gas street engine going in a real street car.
