I have been waiting for almost 2yrs for an A bank, 1990, v12 head. I have an order in at Coventry West but for almost 2yrs they have not come up with one. I have been waiting for Coventry West because they say they pin the valve seats and I would like to get one with the valve seats pinned.

Hi Rob,
I’m sending this as a response. My email to the address shown above in the header block has a problem and got bounced.
How much for the heads and the block?
I have had my heads off before and my pistons all have an outer ridge/ring at the on the top of the piston surface. For the top of the piston surface, this gives a concave surface. The ridge top is flat and about 1/4 wide. Like below.

Also the valve areas in the head are recessed.
I don’t believe these parts are from a 1990 HE. Is there a way to distinctly tell whether they are or not? The sides of my block do not have the casting grid lines shown. My block is smooth.
