383 with Eddy heads!

Ok,thanks for all the info IQ.I can tell you have been doing this for quite some time.I have only been doing this for 4 yrs and there is some of this Ive still got to learn.I have never used roller rockers but have used stock stuff.This 318 is my first 318 build but did have 360 i built but never ran and sold all of it except the top end that i putting on the 318.This time i ready to run the 318 but that 360 would have been a torquey motor!
