Aftermarket cylinder head debate - who's the best

You post all the various complaints from different people as if you expect to find a head that will bolt on and go.

Ain't happenin.

Any and all aftermarket heads will have to be checked out thoroughly by a competent machine shop before use.

If you don't intend on doing that, then use stock heads.
Makes sense....that is probably why there are folks with issues with suppliers...they purchase an OOTB product that was billed plug and play and they have a techinal issue that could have been avoided by having a second set I'd eyes on the project
