identifying an H.C. head, How?
On one of my coupes, I have a indistinguishable looking head. It runs pretty good so I'm suspicious that someone put a HC head on it. But I don't know. Do the after market manufacturers use some sort of marking system so their heads can be identified at a later date? The engine runs fine so I don't want to rip it down at this time.

Check the compression.

Take some photos especially any markings on the head and post them. Maybe someone will recognize something. You could also find out by running a compression test.

Re: identifying an H.C. head, How?
Stock heads from Ford have a tiny bump just above the water pump below the water outlet. Snyder heads have 2 bumps on the driver side with 5 small pin pricks in each. Brumfield heads are marked with a B-F. Ford police heads have a large B or C cast in them. Other than that all bets are off and you will have to remove the head and check the combustion chamber. I have seen heads with several different names cast in them such as the lion head and a Hoof head I have. There are many aluminum heads with varying compression ratios such as the Thomas and cyclone heads among many others.

Re: identifying an H.C. head, How?
So, what is the expected compression for a stock head?

I installed a new Snyder 5.5:1 head last August in my '29er. A compression test then resulted in 75# plus/minus 1# for each cylinder. Mike in Orygun |
