Many may not know this but offy has a new owner as the last offenhauser with any interest retired. The new owners name is Jason Curtis. He is a young guy. He has spent the last two years rebuilding the equipment, repairing the tooling, and finding a new USA foundry for the offy products. He has all kinds of offy stuff now available, for all kinds of motors, parts that have not been available for a good number of years. You should see the new small block valve covers and mid rise dual four intakes.
These are USA cast and USA machined parts. Here is the rub. You have to buy from offy direct. Any place else is a licensed product (prior to new ownership) that is overseas product.
Jason is really great to talk to, he frequently answers the phone himself. If you are going to get an offy, spend the extra and get a real one. My guess is better quality than the licensed stuff.
Newly cast chevy valve covers, now with a baffle welded in. Small block ford port injected, valve covers, they now hav a side cover for a 235.
