Head gasket was replaced, injectors haven't been cleaned. Haven't done a Compression test yet. Whats a good average number for a 200k motor

I pulled the head off and found that the lifters are different lengths about 1/16th of a inch shorter on that cylinder as they are a different brand. Not sure of this will solve my problem but I know that 6 lifters are a different brand then these to. So hoping thats a start compression was good both ways.

No it has not been converted, the original owner said that he bought some online and the 2 shorter one from parts store. That the place online didn't have a complete set in stock, so idk. Putting it back together today, new gasket and bolts again so we will see.
