Bud:

I also have an extra set of 041 heads, but have been reluctant to advertise them as being correct for a Z/28 even though Colvin's book states they were interchangeable with the 186 heads. I am NOT implying you should not have listed them as such, but am just curious. Have any original Z/28's been documented with 041 heads? Frankly I can't see any difference between the 041 and the 186 other than the casting symbol. Have been told the 041 actually flows slightly better. Also, seems like every Z11 and Z10 car with the original 295 horse 350 has 041 heads.

Thanks in advance for any input.
