Hello, I am new to this forum and I have a 510 with an l20B engine in it, which I am looking to get a little more out of, I have tried to do my research and I have came up with 3 things for some better street performance, a87 peanut head, bigger cam, dual carbs. these sound right? will the head bolt directly to my block and can i use my original pistons? also which cam and carbs do you guys recommend ? any and all help is appreciated. thanks.
