I was just wondering if there is any one out there that has put an E-cam in their combo, with stock heads. It's not a clearance isssue, but I have ported heads and intake, and a stock TB bored to 65mm, and mass air conversion. I'm just wondering because I had a B-cam in it and it wouldn't pass emissions, so I put back in the original. I would like to get alot more out of it and still have the stock look to her (Atleast to the untrained eye), and pass emissions. Is it worth it?
