i prefer valvoline 30 wt 500 miles should be plenty of break in some people say 1000 or even 1500 but I have always believed 500 is just right for a roller motor but if you want change the break in oil at 500 and refill with 30wt then change at 1000miles if it will make you feel better just don't take it out and rev the crap out of it before you hit at least 500 miles i'm the worst one about this i have let them run in the shop to warm up and to make sure everything is working right. then I'll take them on a 10-15 mile test drive upon which on several occasions i have gotten into it but i don't recommened this. usually this is the only time i drive the car before it goes back to the owner so i want to make sure it's right.
