#1 head question
DATUTE1 Posted on: 2010/9/12 13:50
Is there such a thing as a h87 head? I checked the wiki and couldn't find anything. I may be going blind!
If so are they any good?

We do not know. There are dozens of A-series heads. What features does your head have?

Aren't these one of the round port A14/15 heads? Some pictures would be great, I have never seen one personally.

A-series Cylinder Heads, see section "H78"

But datute asked about "H87"

Yeah i saw what he wrote. I read it late last night and it kept me up a little trying to think who it was that was talking about one recently. I can't remember if it was on here or elsewhere.

But I was sure it was described as a round-port head with the same combustion chambers as the h89....but I've probably got it all wrong.

H78 is a round port head. Your photos show an oval port head.

It looks to be an open chamber type, which is not optimum.

Why do you call this an H87?

I have an H85, but never heard of the H87

DD quote-Why do you call this a h87?
That's what the guy told me it has cast into the top of the head. Never head of a H87 either so I thought I'd ask.
