Was this a quote from Randy Repp / Goatzilla Racing ?

And has there been any further update ?

I received the most recent edition of Poncho Perfection. In it is an article written by Rocky Rotella on the heads and the bench flow test results. Good numbers if you ask me. BTW, Rocky Great article.

In the article the numbers are from Randy Repp of www.PontiacSpeedShop.com

Valve Lift Int/EXH Flow
.100 76/72cfm
.200 147/124 cfm
.300 213/156 cfm
.400 258/177cfm
.500 269/195 cfm
.600 289/202 cfm

According to other information the heads go for $1,985 per pair at the above website.

Hopes this helps.

Those numbers are for the "as cast" heads, not the cnc ported ones

I checked the site. Here is a link. If I'm correct, it looks like they are available for $2,750 a pair.

Couldn't find Bench flow numbers.

It would have been nice if the heads had been flowed by someone else and Rocky had not just used the manufactures flow numbers.

I found this video interesting

Rocky flowed them and as the article states, "Intake airflow peaked at 279 cfm at .500-inch and 290 cfm at ,600-inch"

I still haven't had a chance to flow the CNC ported heads.

Randy,
Sorry, but I did not read the article and could only reply to what was posted about where the numbers came from.

All good Stan. I'm amazed how little response we get from that magazine. Including our ad we have 9 pages in this issue and this is the only time I've heard anything about it.
Not bashing the publication, just wondering how any people subscribe and read it or any magazine these days.

I think Bernard still does SM O heads, but know the new series E heads came out. I do recall he was sending some back that didn't pass visual inspection, and he didn't recommend using them out of box.

Shipments came in waves, and no telling when the wave(s) would hit land.

Between those two situations, I guess there was a lot of money tied up in the wind, and may just be doing more E heads now.

some flow numbers for us.

Vast improvement over their "off the shelf version".

Did it come with flow numbers?
