Procomp cylinder head

[Graff Spee]

I used two differant sets of these heads on two engines . One circle track and one hot street car. both were just fine for the class or application. I wouldnt use them for my race car but I dont think thats what they are for. I feel that they fill a niche. Thats all.

heads

Heads/blocks are the foundation for an engine buildup, cut corners, and you will pay more in the long run. Brodix is the ONLY choice for aluminum, Dart for cast iron. Both are still made in America.
We sell Brodix at or below jobber, so the cost isn't nearly that much different as most people believe. And they DO NOT need anything done to them when you get them, we have them set up for YOUR application, the Serdi valve job is good like it comes.TB

If you guys are using that Pro Comp crap, then you really cant afford to do any racing.
I had a customer bring me a whole lot of there stuff to assemble his engine & I should have charged him double as it took me twice as long to try to get their sh*# working HALF reasonable. I did however tell him that there is NO warranty. Pay peanuts, you get monkeys, not horses

what race motor is warranty anyways ? no race motor is made to last their made to take apart every year and redo some sooner than that . and it doesnt matter what brand you buy as far as i know all goes trew the same forging shop its the machine work that you have to worry about. Idc if its name brand or off band you should always have it checked to be safe they can make mistakes. i had set of eagle rods i bought brand new and they where out of spec on the rod journal bores and had to be resized. same problem with the procomp stuff just have it checked out by a good machinest and you will be fine.

This is not correct for several reasons, the most blatant of which are:
#1 there are MANY off shore forging business and only a few USA/Canada based factories. The differences in them are HUGE.
#2 the company that purchases the casting dictates the casting tolerances and the metal mix that is used in the casting, the tighter the tolerances and better the metal the higher the initial cost.

Even if a Dart and Pro Comp head came out of the same place it IS NOT the same part!

oldnelly, as far as chinese rods, yea they probably have 90% of them go through the same foundry.
But you couldn't be farther from the truth on heads. Brodix has their own in house foundry. I know, I go there 3 or 4 times a year. When they develope a new product, it is done, cut up, and redone until it's ready to sell to the public, unlike other companies that are at the mercy of whoever they are farming it out to. TB

thats true on heads stuff like that im just meaning alot of ur eagle ,scat and that sort on ur bottom end are chinese made anymore thats why crank and rod prices have went down from what they used to be. but if someone was on a bugget and didnt have alot of money like alot of us races i dont see why they wouldnt work if u had them checked good. Alot of us are just out their to have fun and dont have big wallets like the guys running up front that out spends everyone to win like i seen one guy comment at about money. ive ran scat,eagle, manley and procomp ive had problems with all them and it all fell to bad machine work ive never seen one fail because it was a bad part it was either not enough bearing clearnce or it just wasnt put together right . but as far as heads ive looked in to the dart iron eagles and they will out flow the procomp heads.Theirs a race shop -machine shop on ebay that sells alot of blem and second dart heads that may have a wrong casting number or of that sort he sells them cheap ive bought an ran a set from him for 4 years. its terry rosebush motorsports here is the link for someone that doesnt have alot of money. i think u can get a bare set of darts in a pair for like 389dollars. http://stores.ebay.com/Terry-Rosebus...id=p4340.l2563

inferior heads

Put those Pro Comps in a washing machine (jet sprayer for auto parts), gasket surface down, and see how many seats are still in place when they get to 180 degrees. TB
