91+ valve cover on a 87-90?

I have heard from some that if i put the HO valve cover on my non ho, that the newer style stuff will help me eliminate blowby...is this true?

TIA

Couple of things

First you would need to convert the Valve Cover

Then see if the following fix would work. BlowBy

My Xj is a '91 the BlowBy fix works well for 75K+Miles, then you need to just replace the parts again.
