This is the stock E head. No porting once so ever. Very trick seat work
Interesting, are Ti valves allowed in SS?
Monty these are stock E heads. Those are very light weight stainless. I have them here.

I have in shop. I’ll weigh them later today and get pics for you.Just to double check my flow bench guy didn’t make a mistake. We flowed the prostock heads around the same time they did have ti valves. I bought the whole setup from a guy that had them built and didn’t use. A fella in virginia built them.

I've included a picture of the ports compared to a yates heads with a lot of work done. The Yates heads have smaller ports and flow 390 CFM at .800 with a 2.150 valve
Fordified are you guys holding your own in ss class? I haven’t kept up to it lately and actually didn’t know if anyone running anymore. I have a friend who used to race stocke with oc head. That car ran a high 10.

Monty the flow bench operator got the valve weight wrong on there. Those were Ti valves from the also posted ps head. There is correct weight for stock E valves.
