SS/CS Chevrolet Cylinder Heads...

[SSDiv6]

This was part of my communication with Pat at NHRA...

Hi Pat,

The cylinder head is the Chevrolet GMC 6.0L, LS, LQ4, Cast Iron Cylinder Head, P/N 12561873, Casting Number 873.

This is a cast iron OEM LS cylinder head.

Regards


His response...

Yes, that would be an acceptable cylinder head for SS/CS.
