Clarification on '69 Camaro L89 head design
I have noticed on a couple of '69 Camaro L78/L89 optioned engines that they seem to use a head that does not have the pipe threaded plug on the end of the head.
In the Corvette world, no '68 or '69 L71/L89 optioned engine had an aluminum head without those threaded plugs.
What's the story with these heads? Thanks.
