6 bolt heads, o-ring heads. Just looking around now for a set f heads for my build and I was just wonderign what is the problem with O-ring heads.... seems like alot of you guys shy away from these? I thought it made thingsmore dependable, for th e price to hae a set f heads machined and wire put in is next to nuthing to make sure you have awsome seal on a boosted engine..
Im looking for an agressive 6 bolt head but why not go ahead and o-ring them as well I am wanting to build a retarded steet car and decent track engine for it I know 1500 hp is obtainable now as many ppl on here are striving for it. so if anyone has soe good sudjestions on 6 bolt heads let me know.
As well if anyone has any reasons NOt to o-ring a head let me know as well because im under the impression its a failsafe yes more money but worth it in the long run no?
thanks guys

I had my Dart's225 o-ringed,just because of the thin deck height. I thought about doing the AFR's as well, but will try it first without them.I personally like the extra satisfaction of knowing that they were o-ringed and that it helped seal the combustion chamber under alot of hp.
There two problems with o-ringed heads. First is that you can not use a MLS gasket with them. You have to use a graphite type of gasket. Second, you have to be very careful handling and/or installing the heads. One small nick, scape, or ding in the o-ring wire can cause problems.

replacing the oring isnt that hard if the heads already have them though.. ? I assumed for longevity and security take your time get the heads oringed and run a good set of gaskets and youll be set for quite some time.

Obviously you have never used o-ring head's with these gasket's. O-ring heads work perfectly fine with these mls gasket's!
