Well I got my heads back from a local porter, I was just wondering what you guys think of the job he did, I am not very knowledgeable when it comes to things like this. I just wanted something that flowed better than stock to get the most power possible out of my new top-end setup without breaking the bank. He charged me 1000$ (canadian) for working and porting the heads and intake manifold, and reassembling the heads with the components I bought, and Flowing. I get a free dyno session also (the same dyno where I dyno'd stock so I can get a good comparison)

Here are the pics:

sorry about the bad quality of some pics

And here is the flow sheet
The heads were flowed on a SuperFlow SF600
if the pic quality is poor then here are the numbers:

lift/int./exh.
100/74.0/56.2
200/137.7/103.5
300/193.9/132.6
400/236.9/156.8
500/265.3/170.1

From looking at other flow sheets of ported LT1 heads, the intake numbers seem pretty good, but the exhaust seems a bit low compared to others I have seen, is this a problem?

And finally do you think these heads will complement my 230/236 cam well? Would I benefit a great deal from a custom cam instead?

All comments/criticism welcome.

Looks pretty good,got pictures of the intake?

97Z-M6

the intake could be a litle better but nothing to complain about. but the exhaust look pretty low. the cfm at .500 compared to other flow sheets is about 17 to 20 cfm low. but remember the exhaust is forced out.

Consittering the size cam you will be using, I would consitter having the exhaust side redone. My heads done by Loyd flow close to 200CFM on the exhaust side. I beleive stock heads flow about 150 ish.

On the plus side, you paid a fair price.

As for the exhaust numbers, should I get the exhaust ports redone? Should I have expected more for the price that I paid?
