So was making some DIY head porting videos I have been posting.. These are the final results started with good cores and did some handporting on them I used to do cylinder head and induction systems development. But now work for a professional race team and do this as a hobby.. Heads are nicely ported with stock chambers int port volume is 228 exhaust is 85 cc stock guides valves and springs included.

Heads have not been milled to my knowledge I can cc test the chambers if you are interested in knowing the chamber volume..

Also interested in trade for ls6 243 cores plus 500 cash or I'd really like to play with some other cylinder heads for maybe a l92 DIY video

Any flow numbers? I'm really interested

Let me look Into the cost of flow testing.i believe about 80 dollars

Dam they are nice. I have a set of 243 heads but they are bolted on my car. Would love to have some hand ported heads. They look like they would flow great and make lots of power.

Taking them to get some flow numbers I have about six serious people interested but may be doing a DIY on the exhaust ports m. So I bought 2 more sets if anyone is interested. I will have flow data hopefully tonite..

So heads were on the bench this morning I was pretty happy with the result as was the guy running the bench.. We agreed there is some more flow In The heads after a valve job and some nicer profiled valves also with Some chamber work this would all increase flow at low lift. these heads were 224 cc's and 84 on the exhaust and flowed on a 4 Inch bore port velocity's were very good.. Excuse the pic the heads were dirty the got stained in the ultra sonic cleaner someone put krytox grease in it so the only port I cleaned was the one that was flowed.. We did take a junk exhaust valve and put a small back cut and it hit 303 cfm but we scratched that number since we are only using stock valves.

So what is everyones general opinion on the results?

You can compare them in tony memos thread.. I'd say for the price it's a good deal the exhaust was a little soft IMO but I didn't have a pipe to flow though. The low lift could be improved but that comes with doing a valve job and maybe a little chamber work with in shrouding the valve and adding a nice style valve like a Manley stainless.. But that all come
With money thes are a 40 cfm improvement over stock on the intake at peak lift. On most cams.
