Thank you for advice, but it was too late. I went with SCAT with ARP2000 bolts. Got them new for 430$ shipped so I didnt think too much and just bought them.
Why 20w50?? There is no reason to run that. Use a quality (by that I mean an oil with a base stock of Group IV and V base oils and not Group III) 5w30 and don't look back.
Unless you are burning methanol or something there is no reason to run that grade of oil.
