85 roc it

Anyone have any experience with procomp heads. I was looking at a set of 210cc aluminum heads with 2.02 amd 1.60 valves. Was looking at buying a set but not sure.

Bump this. Wondering the same. Did you end up getting them?

Nope, going with AFR. Everything I read says junk There seems to be a couple of different Procomps, depends on the spelling.

These Blueprint Engines heads seem to be good from reviews I've read:

I'd probably go with those over Pro Comps. Even though I think the blueprint heads are cast overseas, they go over them pretty well and do all the assembly and machining stateside. They dont seem to be a build for the lowest bidder style cylinder head like the pro comps are.

I think Pro-comp heads are geared towards budget dirt racers and claimer engines. With extra porting work and some parts swapping they can perform well on 400+ cid engines on the track.
For a street engine you will get better performance from AFRs, though they do cost more.

I personally ran the 210cc casting on my 347 stroker in my 95 mustang gt. The shop who sold them did all the work 1pc valves matched springs, gasket match ect. I produced 457whp na. For me I reached my HP goal. I also ran a 100 shot with a zex dry system. I never had any issues with the heads. So for $650 for me it was $ well spent. I would never buy them from anyone but my builder bc I know at that point I'm getting a quality upgraded head. Are they as good as my darts or afr no but what power and purpose are you shooting for in the end should help u decide what works best for u

Just put a set on my 383... had to send one back because the rocker arm studs were drilled about a 1/4" off. Basically it is taking a gamble, they are really cheap for aluminum heads and they make okay power for the price. I only got them because money was tight. If you can get anything better, do it.

I initially thought it could be a nice gain for the money, but then I did a massive search on the subject. Ultimately, I came to the conclusion that most of these people ended up spending a few hundred over the baseline AFR heads just to perform below the standards of competing heads. In the end, it's not worth it unless you simply want to see what you can do with the heads. The initial cost may be cheap, but you'll more than pay for it in the long run. I've also seen many cases where head geometry wasn't exact and required machinework in order to correct things. I've heard of more problems with the big block heads over the SBC ones. I know one person who's got a set. They don't have any problems, but they also don't push the motor hard and certainly didn't build it for racing. I also think they happened to get lucky on theirs.

Because of this, I ended up going with used Dart Iron Eagles for the same price from a machine shop completely freshened up and ready to bolt on. At least I can be fairly confident in the quality that I'm getting in that regard. Better safe than sorry.. and look at it this way - AFR/Trickflow/DART hold their value for a reason. Try reselling a set of Procomps and you'll take a major hit on them. Not worth the risk IMO.

Bad castings, voids in casting material, valve seats falling out, machined wrong, pretty much everything you DON"T want in a head. Chinese junk.

Buy a head and experience it for yourself before you spread other people's rumors. Ive used these heads for years along with several local racers beating the tar out of them with good results for the money. Worst issue Ive found is one of the ACCY mount holes is drilled wrong and the raised runner limits intake choices to vortec specific ports

Never cracked a head, ported into a pocket, had any issue with a seat, cracked a head or had any important holes machined wrong

Also, they're cast in two foundries. One in Australia, one in New Zealand. Neither of which are in China. Get your facts strait before you bash something

I know Skip White is well known for his Procomp heads. I almost bought a set from him just to see if they were worth it on a street motor. That's where I would go if I were to get a set.

You get what you pay for with heads. Procomp are at the bottom. A lot of people have problems with them. I have AFR 210. Yes they are a lot of money but worth every penny.
My 383 make 521hp at 6500 rpm. Your not going to get that withy procomps!

Actually those type of HP numbers would be a piece of cake with procomp heads...

But that's besides the point... The *fact* is that Procomp are design thiefs. They directly harm the companies that spend the money on research, development, and quality control. Is it really worth saving a few bucks and in the end putting the innovative companies within the automotive industry out of business? Not to mention risking your entire engine on some chinese casting that may or may not fail at any moment?

Edelbrock, Holley, MSD, AFR, etc... all companies you are slowly but surely killing by buying this stolen chinese ****.

Castings can be ok at times, but I've heard alot of reputable engine builders say stay clear of the parts they use. Some say even the castings can be bad but if the casting checks out, I'd upgrade the valves/springs/etc. At that point you lost any savings in buying the heads. Like said above, some have used them with success. Some havent. Like most parts out there, there are bad apples. I've heard AFR heads having valve heads snap off....things break in racing. You want things to live, sometimes you have to spend alot of money but even then, its not guaranteed.

If you want a good head for the money, check out the Jegs brand head. Its now a casting from Pro-filer (or profiler, i've seen it written both ways) who is based in the US. $580 a head with decent parts. Should work well but again, with buying ANY off the shelf head, you want to be sure the springs suit your cam. If you can buy the heads without springs and put on the right spring for your application, thats the best money you can spend.

Also check out Profiler heads from several vendors. Chad Speier from Speier racing will set up the profilers with his economy port job which gains a few more cfm and ponies, for 1400 or so a pair with components matched to your setup. Cant beat the bang for the buck there. Custom head for your application and made in USA.

Dart also has a budget head out that should be good. Dart SHP heads now, just like the SHP blocks they make they carry the SHP name. $465 bucks a head assembled! Not bad. The stock dual spring may work for most hydraulic rollers but may need upgraded for the most aggressive cam lobes out there for max power efforts.

I wouldnt run procomp since there are better options out there but thats just my opinion. Valvetrain and heads are not something to skimp out on.

I know Skip replaces the hardware and checks all of his cores. Look at his ebay listings and it will give you a full rundown.
