Are you looking for a 12-Port for an early Chevrolet (216/235/261) or for the early GMC (270/302)? If you are looking for an early 216/235 head (15 bolt) Pat Ganahl has a very nice package for sale. When it comes to the GMC heads there are several options available generally priced from roughly $3000. on up. If I can be of assistance give me a call at 253-307-5255
