Talk to the main man in Manchester, they're 'unobtanium' according to him and I've just spent a shit load of dosh with him and I need to recoup something. Just giving you peeps the heads-up, always open to negotiation to serious buyers.

They must be the gold plated diamond studded unobtainium version, I bought a set brand new from St Paul's HD for little more than half of that when the MoCo pulled the plug, just saying
Good luck with the sale

Hmmm, how long ago was that? I also had an S1 that had some from a HD dealer for £600 the pair 15 years ago! Now on eBay is a standard Sportster single cylinder head (unused) £600. Can’t see any other T-storms for sale anywhere at the moment. Maz seems to know what he’s talking about. Just saying 😉

I thought you had to change the pistons if you used Thunderstorm heads, not according to the EBay advert.

Depends what you have installed already. On a bike with flat top lightning pistons, yes thunderstorm pistons are needed along with the heads. That's partly what makes XB heads a better upgrade path for lightning engines. XB heads work just fine with lightning pistons and the XB heads have the best geometry of any factory Sportster style cylinder head. I cannot understand why anyone would pay huge amounts of money for thunderstorm cylinder heads, but it's a free world.
