So I got home from work, in a good mood to work on stuff so I put in some oil, did some little wiring I never felt like doing....Go to pull out on the main drag start to get on it a little in 1st..Vrrrrrrrrr...around 3,000 rpms....POP! Clack Clack Clack....pushed it to a parking lot with my friend pulled off the valve cover and found this ......The base part was still on my rocker stud and the roller piece was chillin next to the exhaust valve spring. Top of the spring retainer was a lil beatin up but nothing deep.... I got these rockers from a guy I got a motor I got my heads from, they were brand new but they look like cheapies, he said they were Ford Racing but there's nothing printed on them so moral of the story buy Quality rockers......Sure glad I didn't go to the swap meet today, woulda been stranded alot more than 5 mins from my house....
