Hey Guys,
I have a 21 stud flathead with Eddie Meyer heads. My research shows that the heads are rated 8.25:1 CR but my heads are about 89-90 lbs at each cylinder. If my math is correct, this comes out to around 6:1 compression. The engine was built by H & H Flatheads and has about 800 miles on it. Any ideas why such a discrepancy? Richard |
