All I can say is well done:). I have mannny applications for that stuff. I not sure how it works though:confused: Does it freeze things so they shrink?Quote:

on assembly of anything likely to seize and cause greif latter on.
Some discussion may start on so called head gasket sealants soon. I will leave it to the UL experts. I mostly do Diesel here.
Project is going well as expected :) there were a few issues earlier but seems to have been ironed out , I've been down to see BD this morning & dropped off the intake manifolds and both heads to have 'em serviced and shimmed and everything "port matched":cool: I also wanted the exhaust extractors ports matched which will make some difference,
but my "dilemma" ATM is the extractors on the passenger side won't pull up/out on as they keep fouling on the side of the Block on "extraction" , and can't be pushed down from the side of the Block as the foul on part of the chassis, so "should" I leave it where it is and forget the the whole idea of port matching of the zorst extractors :( but if it makes a difference to the performance I'd rather take them out now and drop them off where all head work is getting done.
Are there any suggestions as to "how" I can go about doing this ????

Will The Rust inside the bore on top edge of "cylinder 7" be a problem?
The Blokle who lives next door is a semi-retired mechanic of 36 years or so and owned his own work-shop , he once told me I "should" use Anti-Sieze on Bolt Threads on assembly which would make it easier to pull things apart later-on "if" I ever have to take things apart again :(Quote:

All tho the picture is deceptive brown .... DO NOT remove this ring of carbon .... to this or any of the other bores .... as it is a carbon build up that acts as a combustion sealQuote:

Tomorrow ..... Tony will be on your door step .... so A lot of the niggly Q's can be dealt with "on site" .... as some things are fairly hard to explain
Anti Seize or not to Anti Seize ..... This is the Question ...
Some areas require it .... and some areas it would be a disaster
Exhaust bolts are good for it .... Very high temps
Also most of the mongrel bolts that you nearly broke the sockets on
The Power steering pulley bolts ..... NO ... allow them to seize
New Head bolts .... Only if BD or others tells you to ...

I assume your engine does not have the later stretch type bolts. If it does they're a no goer for a second use. The non stretch type can be re-used ok, but of course new ones are even better insurance. By far the best option though is to discard the head bolts altogether and fit a set of ARP head studs.

ARP head studs (google is your friend)
ARP web site
Khos, I do not think that you can fit the heads down the studs with the engine in the car. I do not know this but common sense suggests that there is no room at the firewall.
Maybe someone can respond who has fitted heads in situ with ARP studs. I would be interested as I think they are a good sealing solution but pretty impractical if you have to take the engine out to repalce head gaskets.
Re bolts. The stuff recommended to me and what I use is not anti seize but bolt sealant. this stops water etc going down the bolt holes and causing them to seize. it is a Holden product and you get it from Holden dealers.
It does prevent you retorquing the heads.
Re extractors. Do not worry about port match. Unless you are having extensive work done on the exhaust ports around the valve bowl there is nothing to be gained. In fact in theory the extractor diameter should be larger than the port to stop gas reversion. You will find that this is the case with a Rover V8..
