I have run spray Bar Oiling on both of my big motors. Both with .800" cams. Never any problems with wear and both are street cars. I think that setup helps cool the valve springs, which is good on a street car.....
What spring pressure and lifters are you using for .800 lift to live in the street??
I use Iskys bushed E-Z roll max lifters. They are the only lifters that have ever lasted on the street for me. Needle bearing lifters always failed on me.
Springs are PAC 1224. 275# @ 2" approx 850#@ full lift. I change them out every couple years......
