I recently got 4-1 headers installed on my 96 civic b16. When I got it back from the shop, I was told the headers are only about a 1/2 to an inch away from the oil pan. Also the Slave clynider valve is resting on the headers. Please advise on what to do. How much clearance shoud I have from the oil pan? I have included some pics of the problem.

 

is it an ebay special? its sittin lower than your oil pan that thing is either going to dent the first time you hit a descent bump(which will lead to you buying another one) or its gonna get ripped off
