Cylinder head back in house

I picked up the head on Monday and finally got around to taking some pictures. The work was done by Motor Tech Machine, Inc. in New Bedford, MA.

The work done consisted of (6) new SS valves (2 were bent by UPS driver when he dropped head on driveway), all guides, retainers, (6) new hardened exhaust seats (2 of the original were burned). Naturally, all valves were ground in properly and spring heights were checked and shimmed as needed .The head was CC'd per Richard Good's chart and subsequently machined for 8.75 compression.

When I bought the head from ebay, it was supposedly a 10-1 ratio head and it had been resurfaced. After checking for cracks and doing the CC work, Bob at Motor Tech had to remove another 080" to get it to 8.75 to 1. I was very happy about that, as I didn't really want the higher compression.

I can't get a clear picture of them, but Bob was able to find the proper size for the stems, but very small valve seals, similar to what was used on the old Chevy engines years ago.

Total cost $587.00

The project is growing day by day. I'm beginning to feel like Tom and Bill.

And yes Bill, I do have a line on a few late model TR6 blocks for a "potential" winter project.

Lookin' mighty sexy, Paul!
 
Thanks Doc. I can see this slowly going from a "two extra quarts of oil per year leak" to a Mega $$$$ project.
 
They did a nice job. Hope those valves were not bent on the spring end. That would have made it fun to get them out.

Sounds like you went pretty much the same route as I am with the SS exhaust valves and all. I am going to a little higher compression so we can compare notes when they are running.

So, you going to let the seller know that you had to take more off the head to lower the compression to 8.75? /bcforum/images/%%GRAEMLIN_URL%%/laugh.gif
 
*shh!*

Too LATE! /bcforum/images/%%GRAEMLIN_URL%%/laugh.gif
 
Much too nice looking to but back under the hood. Leave it where it is , or maybe the coffe table in the living room!
 
Paul, Beautiful.

Am I understanding correctly?

You bought that head on E-Bay and then had it
professionally rebuilt for under $600. ??

It looks brand new from the factory.

I envy the low prices and professional work you
folks in the States are able to obtain.

Looking real pretty. If you don't particularly need
to install it in your car just this minute, I can offer
up Crypty's block as a temporary storage site.

Yes, Tom, it would have, if we cared about the worn out guides. The wear actually made it easier to get them out. That, some oil and a bigger hammer and punch.
 
Yes Dale. That is what it cost. I paid $175 for the head. I may have a little more in than others, but I know what I started with and saw how everything was done along the way, so I'm happy.
 
Paul, pardon me for being dense, but when you bought the head it was high compression (10:1)and you lowered it to 8.5:1? How did you do that???
 
Bill, I only said what I was told when I bought it. When I took it to Motor Tech, I asked that they first check it for cracks and or leaks of any kind and then to CC the head to give me the true compression. The previous owner may have been told by the machine shop that first did the resurfacing that they took it to 10 to 1, but they did not.

The first thing that Bob at Motor Tech said when he saw the head, was how thick it was and that there was no way that it was machined down that far. He has done many TR6 heads for racing applications and knows each of the styles very well.

Besides, everyone knows that to raise compression, you have to first add an inch or so of bondo and then plane it down level. I used no bondo on mine.
 
Bob coated it with "machine gray" to prevent rust. I'll just go with high temp black to match the rest of the engine.

Well, that is if I use it on my current engine, which is black, but I may have another option soon.

This is all your fault, you know.......

You and Tom and Shawn and, and.........
 
Seems a shame to make it black; it's so pretty.

What's this about other "options", you holding out on us?
 
I have a friend checking out a couple of TR6 blocks and I may build a "spare" engine over the winter.

The key word here is "may" build a spare.

That's my story and I'm stickin' to it!!
