I was curious what all is involved in the 1.6 roller rocker upgrade. I am most likely going to do this as soon as I get some time to, but I was wondering if it just involves the valve covers or if I have to rip into the intake manifold as well. If I have to take the manifold off, I would just assume take it and have it bored out and bolt the 4.3 TBI on. Didnt mean to hijack or nothing, just that Im thinking about doing the same thing at one point.
