valve clearances- loose or tight?

Recommended Posts

So basically I bought a used head and put it in. Right intake was .007 (a tight .007) and left intake was .006. I put a .05mm larger shim in the right thinking it would put me at .005". Well I can't fit the .005" feeler gauge in. Can fit the .004" pretty loosely though. 

 

So should I put the original shim back in so it's just slightly looser than what honda calls for or keep it on the tight side?

Tight is always better than loose. But if it gets difficult to start, check the clearances again. 0.004" loose is fine.

alright thanks. Think I should bother shimming the left intake to .004?  Ocd's kicking in with a .004 and .006 lol

Depends on how motivated you are. I would, but you don't have to..

okay thanks.

 

Running them tight prolongs valve life and is easier on the lifters, correct?

Not easier on the lifters, just slows the valve speed at the seats. More impact when doing this with very aggressive camshafts, but every little bit helps. Just keep intake tract clean.
