Well i have a stock 43k 172 engine ive taken apart and been tinkering with. Ive got a nice ITB setup next to me waiting to be bolted to it, but i couldnt possibly put it all together without having a tinker with the head 
I know a fair amoun about engines, but absolutely 0 about cylinder head gas flowing, i know its easy to mess up and produce results worse than standard but i thought f*** it why not.
I bought the best grinder i could afford (something s**t for 15 quid from maplins
), and it took me a good 6-7 hours just on the inlet ports but im happy with the results. Im going to have it flow benched.
I'll get pics up in a bit.
So has anyone else had a stab on their own? did it produce favourable results? talk to me!
