No this is for the LS engines.

I'm interested in flow numbers for the 250cc cnc heads.

Yes they are, we've used the 205 and 225 as cast with good results, and the AFR 205 and 225's. We are getting ready to build a 434 lsx with a big turbo for a 70 camaro and are debating on trying these or possibly the new AFR 240 head when it comes out. I was trying to get a feel for what people have done with these, I guess I'll call dart an see if they can put me in touch with someone that is actually using them.
