The search for headers ended today. I finally found some that fit. They are from Speedway Motors. They are labeled as Small Block Ford tight fit headers. There is plenty of clearance on both sides. And they only cost $169 unpainted. Much better than $345 for the unpainted Sanderson headers. I painted mine with high heat black paint and they look great.
Just thought I would tell everybody about some headers that will fit and doesn't break the bank.
