They do not make money. They do it because they love it. The cost of racing at the upper levels is staggering.
Big sponsorships, or they're out.The economics of professional drag racing elude me. I can't understand how they afford it. I mean how can you make money doing that?!?!?! From the truck to carry everything to paying the driver, crew chief and pit crew to running and refreshing the car and the car(s). It boggles my mind how they pay for it all.

Just picked up some bare "ebay" heads for a fun, 1st head build project... surprisingly they look pretty good, no core shift at all and the surfaces are true. They have seats and bronze valve guides. Will post pics if anyone wants to see them. Need to figure out what valves (length), springs, retainers, locks, etc. to run in them.

Link to what I purchased.How much were they? I’m interested to see how they turn out

Will keep you guys posted. I may start a new thread once I'm able to focus on the parts gathering and assembly of the Chinese heads. May have my machine shop look at them as well and I'd like to put them on a fresh block (should have it soon) to see how things line up (intake, bolts, accessories, etc.)Yes please keep us updated as you go.

I agree 100%.The TF ports are way bigger. The communist heads look like a porters stock piece.
Would be interesting to see how they flow and what kind of power they make on the same engine as the TF heads. Not asking you to do (bank roll) that. Just saying it would be interesting to see the results.
Good move. There really isn't a reason (other than an extremely tight budget) to try to save $600 buying a cheap, imported head unless it's far from your first rodeo and you know what you are getting into.Great thread. After all my research Im going with the tfs on my rebuild.

Measure the throat, I'll bet it's for a 2.020" intake valve. It's also a 180cc - give or take - intake port volume.Link to what I purchased.

$180.49 each, shipped.

They arrived very quickly (just about 4 business days) and packaged better than any head I've ever received, including AFR which was extremely surprising. I'm guessing they may be the same as the OP's castings - maybe he can confirm?
They reference a 2.05 intake valve in the subject/title, but the description says 2.02. I don't think they are a 2.05, but will confirm.
I may have to enlist Ed's assistance to line up the most appropriate valvetrain to run in them.
Thanks for the information, Ed.Measure the throat, I'll bet it's for a 2.020" intake valve. It's also a 180cc - give or take - intake port volume.
Basically, a stolen DART 180 casting, including the old school 11/32" valve stems. Would have been nice to have unmachined valve guides so a 5/16" or 8mm stem valve could be used. A 2.040"/1.570" valve combo would have been my idea for a 4.000"-4.040" bore size.
If you want to see the possibilities, you need to buy a sacrificial casting and cut it up in a band saw.
They have potential *but* by the time you get things 100%, you're at the AFR 185/TFS-190 11R territory for price.
From the photos that I've seen of the ProHeader castings (from Ed's site), they look (to me) identical to the head that I purchased from ebay. Ed, can you confirm if they appear to be different? The combustion chamber of the ProHeader's at least appear to be identical to the ebay heads.You can look at photos and see the differences in the castings.
These things, for the most part, should be viewed as entry level castings or budget casting where you arene't looking of a lot of HP. and you're trying to keep costs to s minimum.
My opinion. of course
