Andrew Thanks. I know you said that before but for some reason, I was so under the impression that I would have to use the spacers that I just wanted to double check. this is the first time my head has been off the motor. can I re-use my head bolts or do I need new ones?

That is EXACTLY what I need to do, put a 4.0 head on a '73 " block. do you remember if the head bolt size needed to be changed? head bolts are 1/2" on all '64-'06 sixes except '81-6, which were 7/16" instead. that can be handled too. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
