head should be back on monday or tuesday! then its time to get this thing in. Meanwhile, im gonna brag about the finish on my manifold. I had to emulate calidad on this one. Even though im a much bigger cheap ***.

Finally, the head is back from the machine shop. They took .003 off additional to the .002 that was already done prior. So i have just under .01 total between the head and the deck milled out. I had two ever so slightly bent valves, but no evidence of them ever coming in contact with the piston, so im not sure if the valves were bent from the bad guides on the old head and them being loose, or what. Running all the old back cut valves, and the two i had to replace had them back cut to match along with the 3 angle.




and heres a comparison of what i started with when i bought the head that was done by DFE, and what i wound up with after I was done cleaning it up. DFE on the left, my work on the right.





and....just about fully assembled, gotta make some cuts and splices on the harness to get it all tucked up nicely, and finish mocking up some other stuff.

Are you sure DFE ported that head? That certainly doesn't look like any of Dons heads I've seen in the past.

you guys got any pictures of his previous work?

not bein a dick, but splitter way off center and short turn radius' don't even look touched. Just scuffed up. Thinkin DonF would do quite a better job than that.

Oh i know, but this is what i got, and its got the receipt from DFE enterprises, so unless theres another donf out there, i dunno what to say. Only other pics i got from the kid i bought it off of are these...



and this one showing the sequence of porting from left to right, and then of course my finish work.



Only time will tell how it does.

Natural Aspirations

Any pics of said receipt?

Looks like someone's been working out!

It's so hard to make it out, its not even worth trying to take a pic, its a hand written invoice form with a stamp at the top right, its got everything from the specific dual springs, to the steel crower retainers and the brian crower cams that were ordered. The other receipt i have is from dover cylinder head which is for the clean up work which apparently was done after the head was ported. I know the vales were lapped by hand as well, not sure if thats a signature donf trait.

That porting job looks rough, maybe he just sold you a random head he had laying around that he worked on himself and sent you the receipt from the well ported head. I think I could do a better job than that with a 3/4'' chisel.

It's rough, but its not as bad as it looks once i was done with it, check some of the earlier pics i posted. I just wish I could have flow benched it, my friend never finished the new bench in time for me having to get this car back on the road. I know the exhaust side looks like ****.

Natural Aspirations

Idk, not my business really. Although I've never even gotten a receipt from him for anything... Maybe he gives them out for local work or at request.

Lots of guys hand lap valves, I've done it once trying to cheap out....

th3pwn3r

Well whatever the case hopefully it just works well for you.

I don’t think he would make up a lie about buying a DonF head, especially when nothing negative was said about the porting. Maybe this was Don’s very first head? Maybe the previous owner thought he could improve Dons porting with a jack hammer? It really doesn’t matter. We’ve all seen what DonF is capable of so there is no issue here. He bought a used ported head and cleaned it up, nicely I might add.

thanks, i dont see why the kid would have lied about where he had it done at either, its not like don has some amazing reputation on here that it would have made it sell better lol

pm 00red_si and ask him about the fully ported and polished head he had done by don....then had to turn around and drop another grip of money and have it all fixed by somebody else or ask me about how i never did get my shortblock or money back from years ago....maybe one day people will learn

I posted in your thread years ago over your situation if i remember correctly. Oh well, if it works it works, if it doesnt, i still have another head sitting here in my garage i can have sent out elsewhere. I got the head for basically free, as the full crower valve train inside was brand new.

4g hatch

im sure it will flow better than stock. he knows what hes doing with honda motors. its his buisness practices and ethics that suck not his knowledge or abililty

Speedz

Nice build! i'm getting my b20b block back from the machine shop today hopefully!
curious how that blox IM works on a non vtec setup.

BUT, the the Crower valve train parts....

HAHA! Either way I would have cleaned up the difuser/splitter some more.

i follow the pattern with my fingers, so while the picture makes it look horrific, its actually only a small section of the front piece that is like that, otherwise the diffuser is straight. I didnt want to start taking alot of material off because i wasnt certain i could keep the ports the same shape trying to correct ALL the flaws.

Couple things i found out about it today.

1) You need the ITR throttle cable bracket...had to order it.
2) You dont use the phenolic spacers when mounting the fuel rail unless you have extended length injectors.
3) There is no provisions for the purge valve system, IE mounting and vac line.
