ok thanks 71 nova... cool car (71 nova) I always liked those. there is a nice one on ebay http://cgi.ebay.com/ebaymotors/ws/eB...tem=2455230015

If the rockers will be ok I am going to wait to buy the new rockers because I am trying to save to buy better heads

I read somewhere about checking the rockers with a paper clip (small or large not sure??) in the slot while turning the motor over by hand to see if it pinches the clip. Is the an accurate test?

Also read about double nutting the rockers if using used nuts, so I bought some thin 3/8 fine thread nuts, is this a good idea?
