Id say maybe the point is, putting rods heads on a build like this would be like putting 360-1s on a mild cammed 318, its just not a good match.

Id think Rods heads would give some of the 360-1s a run for the money, so would you recommend 360-1s on this build here to run 12-s? At probably over 3k delivered?

If the improvement deal is that big of a factor, just jump to the new victors, where do you stop? For that matter dump the la and goto the new hemi, again where does it stop?

And really low 10-s, high 9-s is not a hard task with the eddies, folks have been doing it for years, clearly not ootb though.

Get the op what he needs here, not the buy my mopar friends heads. Rods heads will sell on there own to the right market if the testing and semi long term use pan out.
