If the heads are not milled, is it ever necessary to get shorter pushrods?

 

If you get milled heads, mabye with a thinner gasket, possibly different with different valves, a valvejob or rockers. I went with stock length but in hind sight I wish I would have got a length checker and checked them.

 

Thanx, thats really helpful. I was wondering if there is a link with instructions on how to use a length checker. I am not exactly sure what to look for when checking for correct length.
