Re: B230F Heads - All the same? ALL 1989

posted by  someone claiming to be r haire on  Fri Dec 8 04:51 CST 2000 [RELATED]

The turbo heads have sodium filled (exhaust?) valves for heat dissipation. True of the B21/23 heads (160, 398) and of the B230 (405, 530 castings).

I do not think the SCP (small coolant passage) BCP difference is an issue with the B230FT. The SCP hangs on to the headgasket much better and is more desirable in the 398 casting series. All 160's are BCP. I think all 530 are SCP, not sure if ALL 405 are SCP.

There can be differences in the sensor positions and threadings as well as a minor change in the porting area as I recall and of course the K-jet heads have injector ports whereas the LH heads do not but basically the heads for any of the red engines are remarkabley similar.

Most of this latter is of course beyond your original question.
