Hi guys, I have a stock 403 at the moment in my 79 Ta. I was planning on adding 3a heads with a big block valve job or #6 heads with .15 shave and 3 angle valve job. Correct me if I am wrong but the stock rocker ratio is 1.5 right? What would be the advantage to getting a 1.6 or 1.65? As I see it keeps the valves open longer and more depending on cam? (sorry still learning).

I may or may not add a cam later on. If I do it will be very mild, my target Hp is about 300 as this is my daily driver/local show car for the moment.
