H/C swap, oil question
Well going to be doing a heads/cam swap and the next few weeks and just looking to get everything in order. One question i have is on oil, i currently run mobil1 5w-30, doing an oil pump with the h/c so i know something thicker is recommended. I cant find mobil 1 10w-40 or 15w-50 on the shelf anymore, except in an "extended performance" package. Thinking that it might be a good time to switch oils, was recommended valvorine vr-1, like a 20w-50. Recommendations?
