Billet head for a Harley? Or? Fordboy
I'm no expert on engine designs, but have no gripes about Heron-head configuration. The not-modern (1982) Moto Guzzi V50 I ride is far from a "turd". It doesn't have "LOTS of static compression" (less than 11:1), no direct fuel injection, and no blower, and doesn't use an inordinate amount of ignition timing. HP peaks at 49, with very usable torque across a wide band.
I run a Heron head Moto Morini and Fordboy is correct�NOT a good design for racing�It is from the earliest days of OHV engine�RobertThe Baron Race Team
so if you give them a rev, the skirt falls offG

I'm going to say a Nascar Cup head, not sure which manufacturer, but I'm pretty sure it is not a Chevy. Fordboy

FordboyGaskets arrived yesterday @ 10 am. They looked good but I was frustrated about how to check them out. Offering them up to the LMS sample gasket seemed like they were "slightly shrunken", perhaps from the copying process.Then I had a brilliant idea!!!! Offered one up to the cylinder head flow bench fixture! It's slightly tight on the locating dowels, but matches up to the bores pretty well. Gasket bore Ø measures 76.6mm on a 76.5mm spec so that is good. I'll also offer it up to the head, take a photo and post it later.An "offer up" to the block will be the final check. Worst case scenario would be some "slight" relieving of the bore edge, something I've had to do before, so I'm OK with it.Thanks to Mark Adelizzi and everyone @ Flatout Gaskets for producing a totally custom piece for an "orphan engine". Mark is a long time gasket guy, formerly with Fel-Pro. We opted to use his proprietary "coated solid copper" gasket material, because of the need to seal the water in the alloy Rover block. If you are using solid copper gaskets with a water jacket, you might give his product a try. Available in many thicknesses. Check Flatout Gasket's site:https://www.flatoutgroup.com/Default.aspxI did take some photos, but I'm just not up to fighting with PhotoBucket at the moment. I'll post them when I have more time.
