So looking in to camshafts the only two I can find that are a performance cam are mega cycle and web cams. The mega cycle cam says that it can use all stock components whereas the web says you need high compression Pistons to run properly. Is there any benefit to either cam is one better than the other? When it comes to Pistons do they actually make high compression Pistons or is that some thing that I wold have to achieve by shaving the head down. If high Compression Pistons are available where can I get them.
