Would this be a bad idea?

Thanks 67Dart273 for the reply,
No i don't have adjustable rockers that is why i was asking about maybe going to a longer pushrod. If I had a burnt valve what symptom would I have? Would there be any harm in trying one of these pushrods on one of the two problem rockers? https://www.hughesengines.com/Index...aHJvZHM=&level2=T2lsIFRocm91Z2g=&partid=23189
Thanks.


Take the rocker arm shafts off and lay a straight edge across the tips of the valves. If any of them are obviously lower than the rest you can probably use a longer pushrod IF that is the issue.
