Sid here . The first 4 valve heads caused problems at sustained high output , exhaust seats settled , alloy between then got soft
, near molten . Currently the seats are integral in a bronze skull , this cast into the cylinder heads . I asked Ken a week ago about this , was it proving durable and he answered in the affirmative . Seems solid now .
The 1600 cc motor at 184 bhp now . 142 ft lbs torque . Said its nearing max development , but he still has a few little tricks left might add a bit more to that .
Marvelous fellow Ken Horner , never brags but a real wizard . Calls me to chat and has even visited our home and shop .
