It appears that the plug is more towards the center in the GNR’s vs the stock heads.
 Is this an illusion or does do the GNR’s use a difference casting?
Welded stock heads possibly?
Also, it appears that the squish is noticeably improved.
Is this a TTA head casting?
GREAT THREAD!!! |
Champion aluminum heads are a totally different casting than stock. Spark plug is also moved closer to the center.
Also, they redesigned the "squish" or combustion chamber for better flow. If you look at the new Chevy LSX style heads the chambers are almost identical to the Champions.
