How much do Aluminium Heads weigh?

They are the Motorsport J302 heads from Ford. They are one of the original aluminum heads offered for a SBF, but I still like them. What I find is a shame is that aside from these heads that I have, I have yet (but I don't actively search for them) to find any with the wide, Cleveland style bolt pattern on the exhaust side. These J302 heads have two patterns on the exhaust, an OEM bolt pattern, and then an angled, Cleveland style bolt pattern which allows lots of room for larger tubing and still be able to get to the header bolts without a lot of problems. Unfortunately, header flanges are no longer made for these heads.

 

Power? They do a good job, but I've got a lot backing them up (headers, intake, cam characteristics, compression, etc. So how much is a result of the heads only is up for grabs.
