Zippy, they didn't feel loose, so i assume they were no more than .0015 small, likely. Cold 20w50 probably hid any extra clearance well. If i pull it apart again i will measure the lifters and bushing bores. The pushrod situation has me bummed. Having to buy new intake pushrods in 7/16 versus 1/2 inch due to different lifter offset, sending them all back to restrict them to .040,etc i have over $1,000 into pushrods alone. Like they say, speed costs money, how fast do you want to go? Well, i am about as fast as i can afford
