There was some issues with the valve guides. Otherwise, nothing comes to mind.


Doing more with less, or something like that.

 What He Said

They make good power.  They definitely got better over the years, but the old ones do pretty well!

I'd rather be a fool who is loyal to his friends than a POS that jumps ship to save face. We were wrong in the end, but nobody can ever call us disloyal. I can live with that.

They came with cheap powdered steel guides, and had screwed up valvetrain geometry.  If left completely unchecked without at least optimizing pushrod length, the guides would often wear out before the first oil change.

For a short period, you could send in the 'defective' first batch heads, and they would correct the geometry free of charge.  The re-did where the studs screwed in, and included different guide plates.  (I had this done) 

With unmodified heads, many reported achieving better valvetrain geometry using small block Chevy rockers...  so if those are available, they are worth a try.

I sent my heads in, had bronze guides installed, and ported them.  They are the heads on the current 306. 

Good Luck!
