copper head gaskets

[macdeb]

Would you?
Seems I may achieve the CR required for a FI build with the use of copper head gaskets, using 'o' rings etc to achieve seal. Question is, would you?

i have been using copper gaskets on my race 4.5 engine for 5 years never a problem,old school.you can reuse them over again no probs.I had my cylinder heads welded up last year because of tooo much BHP inducing plastic industry additive in the fuel . The engineering company who did the work tried for several weeks to persuade me to dump the rings and copper for compersite gaskets which they thought were much better,wasted there time i'm affraid.

Err no, I went copper and ringed and didn't seal, might be ok on some applications , but in the end went for cometic gasket, far better I speak from experience

Hang on there will be someone that says hey copper was good for me ...... Well not when it costs you money..

I have cometic mls gaskets with no ringing, and no problems, Mac what thickness do you need to get your required C/R
Also look at wills rings

Just under 0.5. Whilst some rave about the merits of metal to metal [copper] gaskets, others say don't go near them

Mac are these your Low Comp pistons on classifieds ?

Seems like you worked out what to do with them

They look like mine

You have two people with fi telling you which way to go, I went copper originally with ringed heads and they leaked. Cometic gaskets were not available then, ..... Just go cometic , why make it hard for yourself.

I have copper Head gaskets,i can't say either way but have not had a problem with them

+1 for cometic. Hear good things in drag racing and nitrous circles. My standard elring are holding up but will replace with cometic if and when

The Elrings are as good as stock composites get Derek the fact your still using them you must have things working well together

[macdeb]

But I'm aiming for as thin a gasket as possible, How thick are Elrings/Cometic?

[phazed]

Mac, why not just keep the heads standard and use the compression plates as Neal did?

Not for you Mac 1.2/1.3 mm compressed Im not much use on the Copper & Cometic deal last thing I built used Fel Pro composite HG

Has anyone had galvanic corrosion issues with copper gaskets? They are not metals I'd normally want to mate together...

No nothing and that was after 20yrs. Using Elring composites now tho and as Simon says they are 1.2mm thick.
