1980 Heads ?
I asked the question on the forum yesterday as to the cc's of the heads on my 1980. I was told they are 76 cc smog heads and not recommended for rebuild because the tend to crack easily. I was told to look to the likes of edelbrock etc. When I went to thier site I found only 64 cc or 70 cc. What would be the correct cc to order for my '80 from the edelbrock folks ? Thanx Brent

Were you the one asking about the L-48?
I have a 1980 L-82 that I will be doing heads and an intake on next year and have done some digging around. Which size you use really depends on your goals. I have pretty much settled on the 64cc/180cc Dart Iron Eagles, but my goals are fairly modest. I'm just looking to give my car a little punch, not build a fire-breather. I'm no engine expert but my understanding is basically that a choice there will force other choices elsewhere. You give it a big combustion chamber like 72cc's with 200cc intake you better feed it with the right carb, better have a cam to take advantage of it, etc.
The other thing to consider in all this is that from what I've read the L-48 bottom end is not a great underpinning. My L-82 will reportedly support my modest goals with it's cam but building up the top of an L-48 without strengthening up the bottom is likely to lead to big problems.
Read, read, read and read some more. Search the heck out of the forum. I'm still reading and digesting and even though I have a rough plan I'm still many months away from even buying parts, let alone start getting my hands dirty. Good thing the research part is it's own kind of fun!
Good luck!
