Blew my head gasket already....bit crap.

So...

Im all set to replace it, but I was thinking while its apart what else could i do to increase performance ?

Any ideas people ?

when i blew a head gasket i put cooper s double valve springs in also you could put unleaded valve seats in you head and maybe some head work too

I'm assuming it's a small bore block? Were you using a copper gasket? the new ones are NFG...

Go the ACL Gasket, Part #CP250MT. Available from Repco etc.

While the head is off you can do a number of things, port the head, fit double valve springs, bigger inlet valves etc..

Find out what type of head you have too.

If it`s not valve bouncing the don`t fit double valve springs,,,the extra load only slows the things down

double valve springs are fitted to a higher reving engine to help stop valve bounce or valve "float",,,that`s all,,,by fitting double valve springs to an "otherwise" STD engine will only slow the engine down

simple as that!!!!!!!!!!!!!!

Maybe fit slightly larger inlet valves & open the holes up to suit,,,& if you want to spend some more money & fit unleaded valve seats then do so too, good for longetivity

You should put your heart & soul into everything you do.

Whats the average going price for an unleaded conversion ?

i cant realy remember but i think it was $150 to fit hardend valve seats

Im am under the impression I can replace the head with one that will give me a performance boost ?

Is this correct ? if so, what could I expect to get for say $500 just on the head itself ?

If you are running a 998 or 1098 you can put a 925 or 940 head...
940 head is a bit more work on the Block..(Valvue clearance)
if you can find the 925 head you are a lucky man..I'm still looking

Gaf, you dyslexic are...
it's a 295 head, not 925..

what would the head off a Mk2 Cooper S most likely be ?

Im running a 12G202 head

I do that all the Time

940 is your best bet..but you will need to pocket the block..so the Valvue's don't hit the block.

202 heads can be opened up better than a 295 by GR in Sydney
