I am glad to see a valver being overhauled!
Personally speaking, I think OEM/standard is a good choice for road driving.
Or you could swap to a Williams setup, which would need the longer wishbones from the Williams. (I think you can also use Renault 19 16v wishbones, or 172 Cup wishbones??)
I am not sure if the parts are available New from Renault, though.
If you have the money, overhauling the suspension bushes and Top Mounts is also a good idea
