I am building a 355 this summer. i already have the balanced rotqating assmbly and what not and also the new edelbrock intake. My questions are as follows: will the 306 be able to pass emissions? what other choices do i have i saw something about a 847 whats that? or customs grind...blah blah blah. also i am gonna use my edelbrock performer heads. with the install of the heads they said to use .10in longer pushrods i guess deck height is bigger, but will i need to change springs with the 306 and 1.6 rockers? any input will help. Thanks!
