Any good recommendations for a port and polish around Vancouver out to the Fraser Valley?

What should a port and polish cost with a head skim.

I don't know off the top of my head if there is anybody around here that would be willing to do such a job at a reasonable enough price to warrant any gains you might make? What engine are you doing this to, I assume your Crossflow? The next question is what cylinder head are you using? (I can't remember the type you used)? You might be better doing it yourself but keeping it to a mild matching and relieving of the ports. I have a flat type here that was bench flowed, you can see the difference between it and the stock chambered head.







Something is truly wrong with the image hosting??? Try again.

Hmm,

Yea was thinking about it for the crossflow, mine has the chambered head. Burton does one but it's super expensive

Yes it is expensive but we are stuck with the "Canuck Buck" It is a shame that you didn't consider a flat type head when you first had it apart as you now have the wrong pistons in your block for the flat head and there are not a lot of the flat heads around to be found. When I did my x-flow I bought an alloy head from Dave Bean, they come in a sort of rough form but are easy to port out to what you want. They are also not inexpensive when you add the new (larger) valves, springs and other bits but they sure take a few pounds off the engine weight.

Try Richard Chong at RAC - Lotus specialist and doesn't do P&P but does know many in the business.

When I built up the 1600 engine in my Morgan, I took a chambered head and had the chamber machined off to make a flat head.
Also used 1300 GT pistons, but had to flycut the tops for big valves.

Dave.

Interesting! I had a flat top head I traded away for some Weber's. Probably should have rebuilt the motor when I had it out but oh well.
Posted on Turbosport to see what's available in England..

Priced out a zetec conversion with using the 2000E box and I can get the parts for about £1200.. might look into it more. That's keeping it on the 40s

Minus the motor mounts and motor.

Found this one in Belgium!








I'll be in Belgium on the 12th but I don't think I wanna carry this thing with me my whole trip

Gonna see how much shipping is

That is yet another approach, I have heard that this method works well. You would have to use the more conventional flat top pistons with this specially chambered crossflow head, lighter pistons, but you might have to machine the block top down too?? Do some research on this one.

Didn't the early 681F xflow come with flat top piston? And 711 had the introduction of the flat head so needed the bowl in piston with the cutouts?

The early crossflow had flat pistons in the sense that it did not have valve cut-outs but it still had a bowl in piston like these.

The 711M engine has the same bowl in piston but also valve cut-outs because the cylinder head surface is dead flat.

These are totally flat bellow.

I think the head you are looking at is meant to be used with a totally flat top piston of unknown origin? I seem to recall reading about how they go about doing it and I thought there was some block machining or perhaps different connecting rods??
You best do some research online to get the compression correct, if you are talking with the seller of that head ask him what the ratio is and with what combination of parts and machining.

Good advice, thanks Brett!

Remember, a formula ford head costs serious money and in theory at least does not deviate much from "stock" condition. And they are built in decent numbers allowing the engine builders to get a good handle on efficient production.
My point is that head modification that optimises performance is expensive ! The Burton head might not be all that outrageously expensive if it produces true results. Without access to a flowbench and dyno as well as someone experienced in their use results are very difficult to verify.

I talked to Kershaw Performance in Langley,

Guy said they have a flowbench and ballpark figure was between $400-500 for port polish and head assembly if I supply the valves and misc parts.
