ETP215s at 62cc for me. They gave me an extra 30rwhp on my set-up. I'm running a Comp 222/224 cam, but will be upsizing the cam later on in the year to something that will maximise the potential of the heads.

Cheers,

Macca

I just bought stage 2.5 5.3 heads from TSP but before they shipped out I changed my order to the new R series of that head with bigger valves. They flow over 317cfm@.600" and for the money you cant beat them.

If I were building an all out motor though rather than my DD I would go with either AFRs or TFS.

AFR 225's. Upgraded from Dart 225's. Noticeable difference. Too bad I didnt dyno either combo. All I have to judge by is SOTP.
