Hi All

I know 850's to 1100's all have the same head gasket but would it be possible to put a 12g202 head on an 850 engine??

i am just curious and dont have any plans to do this was just thinking about it

Cheers

Certainly is possible, I stuck one on my 998 automatic and it made a difference.
Best to deck it a bit first, the head volume is a little bigger so would lower C/R if you just bolt it on.
I'd rip .050" off....

so would it be worth it and it isnt too criminal to do to an 850??

cheers

the 850 i got from mad-mk1 had a 202 head on it..


plus you get the new fangled extra of a temperature sender

It's what I run on mine. Externally my car is a very original '69 MKII 850. Probably the only visual mods are the 1.5" carb and the reverse rims. However that didn't give me any qualms installing a better cam and 202 head(cc'd). Makes the car a LOT more drivable in modern traffic. In fact most of our club don't believe me it's still 850

i put a 12g295 head on my 850, I would say 30% more power, the car did 80+MPH as a stock (no rebore) 850 with 1 mod, This head.

what's this 202 head then? and why is it so cranking? and who still has 850's they must struggle to keep up with city traffic now surley I had a clubbie with Drums all round 6 years ago and I don't know how I didn't his someone with the brakes other cars have now.

Try it with single leading edge brakes on a standard 850 ..... I know the 1100 etc head will fit onto an 850 block (running one in the sports 850 at present , but what about a 12g940 head , I don't think they are a straight bolt on even with pockets in the block for the valves , any ideas ? Wondering just what I can get out of a thrash 850 motor ....

the 202 head is the 12g202 head found on 1100s and some 997 coopers

nothing special about it, just flows more than an 850 head, it's cheap and is a good base to start with for porting..



you should try single leading shoes with an 1100 in the hills
