Main girdle or windage tray or both?

[Fulcrum]

I'm new to the forum and would like to say hello. What brought me here is a quest for knowledge on Ford 302's. I am currently collecting parts. So far I have a set of KB Silvo-lit .030 pistons, Roush 180 cast iron heads, Manley Racemaster 1.90/1.66 valves and a Doug Herbert Cam #CF4N. Oh yeah and a '79 Mustang 5.0 garage queen with a '80 Mustang spare parts car along side it. My question's are: I understand from days long past that the bottom end of the 302 is a bit weak when compared to some other engine blocks. I see that a Steel Main Girdle is available through the catalogs. I also understand that a windage tray will increase performance. I intend to use the stock Crank and rods reinforced with ARP Bolts. Can I install the Main Girdle and the windage tray? or is it a one or the other thing as i suspect it may be. I have overhauled several engines before but this is my first "performace orintated" job. Thanks!
