I have read here about people doing grill blocks and I would like to follow suit. I know that I will probably have to do a partial block to allow for cooling.

My question is which grill should be the partial and which should be the full block, the top grill or bottom grill? Or should I do partials on both, but keep each less open then 1 partial and 1 full (e.g. both at 75% block, rather than 1 at 100% and 1 at 50%)?

I have seen people keep the left or right side open, but I am thinking about keeping the middle open in hopes of better airflow right at the radiator, making it possible to block just a little bit more.

Thanks for your help!
