Re: ZL-1 & L-88 head design clarification
I'm not sure about the '70 heads, but the '67 L88 was a square port head, and the ZL1 or later L88/9 were round port.
I'm just going by what the Corvette guys and Colvin say.

Re: ZL-1 & L-88 head design clarification
Maybe on the exhaust side, the intake sides were all rectangular.

Re: ZL-1 & L-88 head design clarification
Guys,
I had often heard that the '074 ZL-1 heads, with their round exhaust ports, we an ineffective design concept. The amount of power required to take advantage of this port design was impractical. In my research on building big block engines, the '077 ( over the counter ) heads seemed to get the thumbs up due largly in part to their "C" shaped exhaust port designs. Can any of you support or refute this information? I see the '074 heads on ebay all the time and often wonder why people will pay big bucks for them if this it truly the case.  Steve
