The CFE 15 degree head with a 287cc runner flows around 405 with a 2.225 valve. That is based on my own bench, not an advertised number by CFE. I would not judge that head by the CFM... There is nothing negative about that head in terms of capability, nor reliability. It's a very fast cylinder head.

My new 15* heads from Curtis I have nothing but good things to say on them, dont worry they where not on my sig. time slip LOL, first thing either place will tell you is, dont buy your heads using just a CFM number, any company that does that is just selling a big hole they flow a lot.

I would like to hear about you combo....bore, stroke, intake and cam. I have a motor sitting on the stand that is 95% done. 4.185 x 3.625 with RFD 15's as well. Used the Victor/Glidden and a PS SV1 (1160cfm). What kind of power to you make?

x4. Either head will work great. Curtis' heads are more custom to your application and can get pretty big in terms of runner size and mcsa. The CFE are more universal but still an excellent head.
