I bought these through the GSCA maybe 20 years ago and they sat in my basement. They are chrome plated and they looked like new when they were first installed in June. They were on for the cam break in and about 10 hours of driving and they are discolored but no rust or dings. They were easy to get on and off no dents required, I didn't have to lift the engine, just had to remove the starter. I believe these are from the GSCAs second run because the flanges are 5/16" thick (I have a pair from their first run and it has 1/4" flanges). I am switching to shorty's for the ground clearance since this is a street car. $500 plus $65 shipping. I will gladly deliver for the cost of fuel from Saline, MI (my car gets 39 mpg).
