Well the head's off now and the gasket is fine......not the same could be said about the valves!!!









Why is the exsaust valves white and the intake valves black? Too lean?
It's a 12g295 head, and now that it's off what should I do to it.....porting perhaps?

foot note: running twin 1 1/4 su's, 1100 crank

Is there something wrong with No1 piston ? it looks to have a hole in it



The exhaust valve gets hotter than the inlet valve, but it may be getting hot I don't know much about these things

One thing I'll tell ya -gotta start running coolant instead of water - look at all that corrosion.

big = intake (as ive finally learnt!)

piston one looks like its just got a drop of water on it
simple work to head = from $600 from mini places

while the heads off clean the gunk you see in the water channels
replace the head/block adapter tube on the head (far left little tube under thermostat housing
and clean the block surface

isnt it great taking a head off a car!

Where are you looking?

I can see what looks like a droplet of water sitting as bead on top of the oil on the piston.

The second photo seemed to look like a hole but I think it is probably not now it might be the reflection on the droplet that makes it look that way, I was thinking it was a very symetrical hole but I wasn't sure how these things formed Sorry didn't mean to panic anyone

I'd be worried about what happened to the rest of that valve (no. 2 exhaust)!!

Oh and practise on a junk head (like 12g202's ... waits to be flamed....), and after your sure you won't bugger it, go to town.

Better yet, sell off the 12g295 while it's in 'pre-worked' condition and get a 12g202 worked fully. Especially if you're gonna have a go yourself!!

Otherwise just clean it up and have unleaded seats inserted, & have it mildly ported. the '295 chamber design is already pretty good, & the ports are fairly close to right already. Can be improved tho'

Good luck
