Hi Guys,
I pulled my cylinder heads off last night and heads being heads there is a heap of carbon (black) build up in there. What is the best way to get rid of this stuff?

Some of the exhaust valves are stuffed also....but I am heading up to Brisvegas next week so will be able to fix that with a quick visit to Micks!

Cheers :bounce

a good fix would be to pack em up and send them off to V Force for a fix up. New valves, 3 angle valve grind and send you manifolds and get them match ported.
Measure your deck height so as you can calculate your compression ratio and get the heads fly cut to give you about 8.?:1
Do this to a 1600 and it will be a nice motor. Cheaper than new heads and a mile better.

I bought some 2nd hand heads and mine even had the intakes practically blocked by carbon,take your bare heads get them glass bead blasted they will look like new and so beautiful,allow 2 days for this,then take them over to Head Jobs Unlimited at Ashfield with your new exhaust valves and your intakes,they know what there doing so just give them a couple a hundred and your laffin,another 2 days for this.:thumb

Or if your in a hurry a small wire brush on an electric drill works fine too,takes all the carbon off leaves the head shiny.A small brush is needed to get in the tight spots.

Depends on how much carbon is in there but i would say that your engine
has not been IN TUNE for some time and neglected.

After its rebuilt make sure you have correct timming and fuel air miture ratio.

yeah glass bead blasting will remove all the crud...
have you removed the valves and is ther heaps of carbon in the ports

Some pretty rough methods there - a wire brush is more than likely to do damage.

Scrape the bulk off with a wooden implement, then soak them in diesel a few days... Scrub them with a nylon scourer and rinse in water (then lots of air to dry and clean them off) to keep them in good condition.

I tried the wire brush with the drill no probs,cylinder heads are pretty hard.:thumb

If you use the wire brush with the softer type bristles(steel) or the brass type ones it is fine to clean up heads with.

to reduce carbon build up dont use LRP if your using it but instead go for premium unleaded
