Just to let you know that I will be doing a complete teardown of the engine and see if I can just get by with a hone or 30 over . I will also have the deck shaved a little . What is a good but reasonable kind of heads that you would recomend ?? Ie dart / world products/ iron eagle/ ?? And what's a good cam that will produce some good to numbers ?? Like a said ..... I'm wanting about 350 Hp .
