I have a stock rebuild on a L-79 327 except for flat top pistons. .030 over. I was looking to add a litle "pop". The Elelbrock Performer RPM
#EDL-60899 is what I came up with. Anyone have any feedback? Anyone try these? 64 cc combustion chambers, 185cc intake runner,m 65cc exhaust runner, 2.02/1.60 valves, 575* max valve lift. Aluminum heads. $1091.00.
They seem like a good bargan. Would appreciate comments.

I'd jack the L-79 heads/intake up and run some more cubic inches under them for that kind of money.
I think you'll be disappointed with the results of just changing heads for the time/money you're thinking of spending. Not saying there is anything wrong with the Edelbrock heads though.
I put on those heads 2 years ago but with the "11:1" pistons.(worked out to be 10.25:1). So far, there have been no problems with them. The car performs better than the old 1.94 valve heads they replaced, timing is no longer critical and the weight off the front end is noticeable. Get the heads that have the cross over passage. Without it, your exaust will sound strange unless you use a pipe cross over.
I've put them on two cars and always with noticable results and no problems. They are good heads and their price is better than most. I loved the savings in weight.
I was looking at the AFR heads with 195 runners. I have not read any tests on these with the 327 engine, only 350 and 383 where they seem to really improve power over 5,000 RPM while performing well below that RPM level. Hot Rod Mag has many tests with Dyno charts you can read.

I like AFR heads but I believe the 180 heads would be more suited to a 327 used on the street. 180 heads will maintain the intake velocity higher on a street engine. If you're going drag racing a lot, then the 195s might produce more power.
I can't remember which mag it was but there was a writer trying to wring the most horsepower out of a 327 as possible. His first 327 build used the 180 heads and he made over 500 horsepower with a not too radical solid cam. His second 327 build was with the 195 heads with the competition finish (over $2k) and a more radical solid roller and he made over 600 HP.
A more recent mag build used an aluminum block with 400ci and they went with 180 heads (Dart I believe). Their rationale was this was a street engine and the 180s worked great on the street. The heads were chosen by the Dart head guru IIRC. The engine made a little over 500HP IIRC.

I am pretty sure those are the polished ones, right? If so, that is what I have. I really like them and have no issues at all. Is that $1091 a set? Mine is a used set that were barely used for $700.
The $1091 is for a set of complete heads. From what I have read the 180 heads are what I need with a relatively stock 327. I want something for the street. Not looking to race it just a good street runner. I want to keep the stock look. The only thing that I don't like is the Elelbrock etched on the end of the head. I can live with that.
