V-twin cylinder heads for a Panhead

#1

Post by whenpancomestoshovel » Sat Jul 22, 2017 2:56 pm

The cylinder heads on my Panhead are pretty much beyond worth saving. They are mismatched, need new valves, guides, seats, extensive welding, combustion room repair and new rockers. For this reason, I need to be looking at replacement heads.

I've been eyeing the V-twin heads for some time. The quality seems to have varied throughout the years. Anyone who has input justifying a spending 1200 dollars more on STD assembly?

Has there been a new generation of V-twin heads recently?

Empirically addressing your heads challenge, with V Twin; it's a hit or miss affair.
They are by far the biggest players, that written they are often the only source for remotely located chaps.
But if I was seriously considering buying a new set of heads, I'd save until I could afford the best out there, always.
So sir as I have written, its a hit or miss affair, you might hit, or you might miss. But with a really good set, you will be worry free.
have a good time doing your research.

As Budda said V-Twin is hit or miss-(Mostly MISS!).I have worked on them in the past,& Dislike them because of the misery that is caused by the stupid mistakes during machining.//If you can find a set of OEMs at a swapmeet /that would be a nice route to take.Recently I have been SLOWLY building a 49fl bobber,& I have purchased a set of STD heads.Very Nice & the QUALITY is GREAT!/I opted for the shovel intake type as it will be a light/hopper with a slight 84-inch stroke.That being said ,my 58flh heads are still going strong/but showing thier age/so I will get eighther a OEM set or another set of STDs but in traditional plumber style.--Respectfully---Richie

And the studs are sticking out of the nuts different lengths. Some reassembly required as with most parts from them.

I'm not in the market for replacement cylinders or heads and it's been awhile since I looked at options but is S&S a bolt on option?

Hello everyone!

I have been lookin for a pair of V-twin panheads from eBay, since my original rear head is completely toasted. I've done some research about these heads, and found out those Made in USA -versions are really nice, but are these imported ones actually that bad? What are the issues, fitment, inserts, seats, cast? I've been looking a set with valves&springs 1955-1962, my original rockers are fine. Would appreciate if you guys, who have been playing with these imported ones, would advice me with the possible issues I may come across buying these.


Thanks!

Thanks for the reply tattoomark!

Well, so there are problems with them. I'm from Finland, so I'm not in the same state with you, haha. I've been tracking some oem heads here in Finland, but if they are rare in the US, they sure are really rare here! I mean nobody has them, or if has, won't sell. My front head is just fine, no repairs whatsoever needed there, but will need a solid good runnable rear head. I've been searching oem heads from eBay also, asked for better pics of one but the owner hasn't replied yet. If someone is holding nice rear head I'm interested!

Just for curiosity i'd still like to hear others experiences of V-Twin panheads. I'm gonna pass them anyway, as a student i can't afford to pay 1200 bucks for crappy heads.

peacemakermichael,

Here is a vendor in Germany that makes complete engines and accessories. Here is the link for the cost of heads.

After years on this forum most will note I am no mechanic so here's a non-mechanic question. If someone has the v-twin heads or other mfg type that leaves a longer gap than stock jugs/heads create, is it possible to have a stock or aftermarket intake manifold very, very slightly lengthened by a skilled machinist so the gap is no longer an issue?

Kevsett,

I was thinking the same thing. Sure, cut manifold, add in new piece weld up.

Just as a point of reference, Motortechnic is who is making BTSV aluminum 74 cylinders for Ted. Saw a set at Oley last spring. They look nice, but have a iron liner and can only be made in 3 5/16 bore.

Yes, it is possible. My issue here is that I'm a student, i can't afford to pay 1200 bucks for heads that require work. I'm sure that manifold issue is not the only issue there. I do not have equipment to do the work myself, so it is not an option. I'd rather have right-priced OEM head that might require slight work or not work at all.
