FYI the 990 castings have cast in valve seats and the 188 casting have pressed ln valve seats.The problem is that if the 990 heads need seats when the try to cut them out 9 times out of 10 you hit a water jacket.So in my opinion the 188's are better than the 990's for the simple fact that they are easier to rebuild.

I don't need a match. I replaced my heads last year. I'm only asking because someone else has found my head as a match to thiers. So I was wondering what I should sell it for. I had a friend that feels it's worth $300. ? ? ?

I have 1 990 head that is decent. Not rotted out , not ported, but needs rebuild. Make offer. Just threw four on the scrap pile Just went for New Dart. Beware of used dart heads. Early castings did not have the cast in struts where they eliminated the exhaust crossover, and are prone to cracking. Dart heads are cnc ported. They are heavy too. Really thick decks, etc... I couldn't believe the difference when I went to pick one up. BBB
