Are these Porsche heads?

[igtoth]

Hi,

I believe those are Porsche heads.. but I never saw it before.. Anyone knows what they are for ?

Regards.

Judging by the angle of the exhaust valves and double rocker studs, they are indeed porsche.

[slalombuggy]

Double rocker studs and angles exhaust valve definitely indicate 356/912 Porsche heads.

Ive never seen a porch with ex port like that.possiably a vw head somebody put the porsche rocker system on & canted the ex valve, something Ive been wanting to do, but no time.(intake valve too.)but the valve cover is not vw shaped.possiably something not ment for us??brazill only? one off german?Idono. whats the spring side look like?casting ##?? the intakes also apper to be canted. if it fits use it!!!I would.

[slalombuggy]

I think you're right Mark, Porsche used a rectangular shaped exhaust port and the studs were level across the rocker box and the shape of the box is completely different

Wrong bore spacing to be a Porsche head, would not fit. Has to be a one off and very rare 40hp and latter type 1 head. I would love to see the rocker arms for it or a dp version of it. Does not look like aftermarket. Been around VW's for forty years and have never seen one like that. Dan

[mark tucker]

possiably the front drive gol? from brazill? and yes it would be nice with duel ports, even single I would like a few sets ready with rocker gear to play with, even add an extra intake port.but just too much stuff in the way as it is, but it would be un to play with & probably make some real good power.

I have never seen a 356/912 head with round exhaust ports and a single intake port also the 356 heads have the lower part of the rocker boxes elongated to accommodate the angle of the exhaust valves. The combustion chambers are also hemispherical. But those are very interesting and would be cool vintage speed motor.

whats the marking in the head(rocker side), looks like a trapezoid, in between the stud stands? also the round print on the right side of the head(top pic)?

Sorry to disappoint but these heads are definitely not Porsche.
Porsche never "produced" a single port head. Even the first Gmund cars from 1948 had dual port intakes. They used VW engine blocks for the first five years, but the heads were their own design. Don't know what this is off but since the VW guys are stumped I'd wager it's something really weird,...like French or some such. Possibly Panhard?...Deutch Bonet?
There are lots of air cooled horizontaly opposed engine designs in the past. Fairbanks Morse? And then there's the whole aviation world and ground power unit world...
Or, like some have suggested, some sort of aftermarket speed development head someone designed and had made.

[mark tucker]

or one of those car companys in brazill that also did some special heads, there was some 356 replicas coming out of there back 20+ years ago. it sort of looks like a single port superflow valvecovered vw ex,port porsche, conglomoration of some sort.kinda like a replica should have, not just a run of the mill vw mill.

[mark tucker]

this is what I have found and it appers to be what I thought.

1980s, air-cooled VW Gol: upgrade for VW Types 1, 2 & 18

--------------------------------------------------------------------------------

1980s, Brazilian built, air-cooled engined, VW Gol (not Golf !): engine upgrades for VW Types 1, 2 & 181

Whilst browsing through some of my old car magazines, I came across an article (Neil Birkitt, " VWs From Abroad: It's not Golf, it's GOL!", VW Motoring, December 1995, pp68~70), about the Brazilian built VW Gol, featuring a VW 13/1600 Type 1 style, air-cooled engine, but with redesigned, twin-port cylinder heads (valves inclined at 15º to the cylinder axis, rather than parallel) and a cooling system with axial-flow fan and integral alternator (akin to the Porsche 911 arrangement), whose fan inlet is at the crank-pulley end, rather than the flywheel end of the engine.

The air-cooled engined VW Gol, went on sale in Brazil, in the early 1980s and it's interesting to note, that the redesigned, twin-port cylinder heads and unique cooling system, were sold by Claude's Buggies (later renamed CB Performance), as a performance upgrade for VW Type 1, 2 & 181 engines. By 1995 or perhaps earlier, the VW Gols, were re-engined, with VW 1600 & 1800 water-cooled, in-line engines.

Regards.

but it is on a type 1 engine from vw. and yes I would run it if I had one or 2 of them, wish I did.
so who proved it? and what were they doing? was it properly done? the typ1 shroud has proven to run hot too.in ohsomany cars.not trying to start shit but I dont see any issue with it I couldnot fix.

and whats the issue with the twinport??that was just copied from another older samba post.(no I dont know how to link them, remember I lived in cali so some brain cells are burnt out) just messen.

[SBD]

[mark tucker]

so the olson twins dont port vw heads?they went from single ports to duel ports(twinport)

[Beetspeed]

Very cool! Never seen anything like that either.

They seem to resemble the above Gol description, save for the twin-port part.
So, have there ever been single port VW Gol engines?
Maybe if some VW Gol's were 1500 engines, single port would sound consistent with VW's prior offerings in head-engine combo's?

Igtoth: where did you found these? Were they on an engine that you know of? Any history of the heads or just the picture?

Would also love another good pic of the chamber

Mark, I know no one has ever mentioned this, but you're ridiculous. I don't see how anyone could ever get mad at you are genuinely argue anything you say. In my opinion you keep things casual and light hearted in these forums and maybe I have a poor sense of humor, but I'm usually laughing at your jokes.
