Hello all,

I'm not experienced with heads and machine work, so I'm hoping you can help me here. I just purchased a set of used heads that were machined for 2.02/1.6 valves. one of the heads is normal, the other appears to have had the valve guides drilled and re-sleeved (see photo). Is this acceptable or do i have to be concerned about this head failing? thanks in advance!

 

anyone?

 

Please... I need to know as i'm planning on installing these this coming weekend?

 

as long as they are guides are tight they are fine and make sure the top of the guide is machined for the proper seals i work at a local machine shop and we normally use bronze liners in stead of drilling for guides but it is not a problem
