I think it's funny you say, "Why read" but then list 13 different cam specs to read.

 

look into the comp cams "503" or cc 224/230. It is a popular grind for stock and mild ported heads. It shouldnt be too hard to get a spot on tune with a mail order guy(Madwolf, Pcm4less).

With LT headers, exhaust, 1.6 rockers, etc. (supporting mods) it should put down 335-355rwhp depending on the setup and if your a M6/A4 an 12 or 10 bolt.
