Alright dumbest question of the year for the beginning of the year. While i and everybody would like afr 195 s, i see many more larger runner sbc heads selling for lower prices. Is it possible for the home enthusiast to reduce runner volume through epoxy or some restrictor i have never heard of? I see used brodix and afr 220+ heads going for as little as $600 and theres everything to like about them except intake runner size and lazy airflow at street rpm's. I am guessing that it would be too difficult to epoxy them and yield consistent results without a flowbench. Appreciate any suggestions. Building a 383 for my 82 ta just for street. All 4340 bottom end. Roller cam comp. About 245 duration @.50. And about. 570/.580 lift with comp 1.6 rr's, and yes weak 10 bolt rear still in it. In search of heads like afr 1034 but just cant pull the trigger on $1500 heads

It would cost too much to have someone qualified do it if they were even willing to take it on
You might be Ok with an AFR 220 on that motor of yours
How its geared/tuned etc will determine a lot not to mention useage.
Have 230cc darts on now and looking to go afr 220s soon.
Sure they make good power and run hard upstairs but imo still too big could be more snappy through the mids.
Not so much the size, its how they work that appeals to me.

I would never buy a used cylinder head and put it on period;they will need something
Thats just me.

That's what i'm talking about! Exactly to the point and immediate. I figured there was a reason i couldnt find related posts or why you guys arent bragging about unporting a set of 230 heads. The same reason we rarely hear about anybody fabbing up a great rear end from the previous generation 10 bolts. You might actually have to know what you are doing! Im sure you have done your research but from mine, i bet the afr's will outperform the dart at the top end and and increase the snappiness down low too. Appreciate the input cuisanart. This will crack you up but i bought a carb not knowing its size last year from a 383 made by pro systems. When i called them to ask, it was a 950! And i have anextra australian 9 bolt and an 80 disc brake corporate 10 bolt. For when all of these parts reach their potential. Its a sickness

Have you checked out Pro-Filer and Jegs brand heads which are same casting as Pro-filer? Very good heads for the money and can be had for under 1000-1100 complete.

Chad mentioned that the profilers that aren't through him have junk parts on them which is the reason why some of them had complaints.. Eg: locks, retainers, etc. I agree though, you can't go wrong with either of the heads, really.

Unless the heads come with a parts list, I wouldn't usually trust the stuff they throw in. IMO the way to go is to buy a set of machined and finished castings and put them together with the parts that best suit the setup.

I understand what you guys are saying. Somehow a reply or two of mine disappeared. I had a tough time finding 195 pro filer bench flow numbers to make an apples to apples comparison. Articles were about 210 or 240 's or fully ported big intake runners by dr j. Ideally i would have a friend machinist who was an expert and did it for half price but in the end i stillfeel like afr has the reputation to keep up and they are 100% responsible for springs valves and everything. If i was the expert then i guess i would want somebody to pay me a few hundred extra bucks for my knowledge and experience. And it does concern me that house brands can be less than entusiastically assembled. It is possible that some manager will want to save money or use up some old stock. I see it where i work too. Getting this right is hard. Paying for it twice is not an option. And by the way i have now been at work 13 1/2 hours straight and may end up working 36 straight if they cant call anybody in. Hey orr89rocz, i work 10 miles from pittsburgh speedway. Brother in law is john groba, runs his red 67 camaro there. Low 12's. Small world. Thanks guys

Yeah dimented. That sounds expensive too. Hey i have an extra 9 bolt and i see you run one. Strong enough as long as i dont get slicks and hook up? Been worried about that

thats what im thinking too. More torque across the board and more (which is already fantastic) top end/throttle response. Putting a smaller cam in to pick up torque is giving up

Some argue the whole "big enough" cross section then flow #s dont matter. I dont buy it. Still saving though turns out my Jesels wont fit the AFRs so theres another 1200 I gotta save lol on top of the heads. Should get me to the 600 mark if not a little under/over. Better start selling porting jobs again cause Obama forgot about me this Xmas!

Sounds like you know what you really want...put aside the funds and buy the best you can the first time. Wish I did.

Keep searching around. You will find some deals. 195-210 cc from most of the major brands will work. Since you wont be turning high rpm AFR with their faster port speeds will make abit more power. Either way you want to be sure the valvetrain matches your cam requirements. I like afr spring packages for hyd rollers but not sure what solid rollers work with their heavier springs. Looks like most non race lobes will be ok to 7000 or so rpm with 220 lbs on seat and over 500 lbs open pressure.

You know Orr think your right.
220s come with sr springs hed have to pay to change those.
Some 195 comp ports would be the ticket for him if he could find some
the new revised ones flow like gangbusters
theres only like 10-15hp diff between those and the 210s

245 roller cam he says, I assume its a mild street solid roller with those numbers... but I could be wrong. If hydraulic roller, thats a good bit of duration and it will want atleast a 210cc head. 220's if the port is done right certainly isnt too big for a 383. Abit of compression and good cam will run extremely well, but it will want to live in the high rpm ranges.

and just to point out - flow numbers aren't everything. They're only a portion of the puzzle, really. All heads aren't created equal, so you can potentially get some awesome 195 ports that work well on a stroker. You're essentially saying the same thing, though. It's about AVERAGES, and not necessarily flow/peak flow/peak velocity.

Its finding the avgs thats the tough part lol.

Im pretty much convinced the smallest head that can pull it all off is the way to go on the street. Tried the "large head can work" thing not so sure its the way to go on the street at least. Track WOT only maybe.
