Quote: Well its like buying a crank or rods.Would you just open the box and install.Yeah you might get lucky but its worth the effort to check it.Ive pulled new oil pumps aprt to check them.Just a caution.Ive installed too many NEW parts at work that were stock replacements that didnt work.With $$$ in a motor Id rather be safe than sorry.Rocky
The same in some ways, not in another.
If they say they are balanced to X then they shoule be balanced to X. If you are matching the rods to a cranke thats been ground and you have to match the sizes then thats another story.
Likewise back to the heads...
If it comes assembled with valves ground they should be ground correctly, seats should be at the correct height.
If I decide to run oversize pushrods well then I should have some work to do on my own.
