Deployed since May, need some advice

Hello all.

I was recently contacted by Buffoni88 regarding the heads that I had but I wanted to help him by seeking advice here (in his thread).
He is asking if the 73cc heads that I have will fit his 318 well. I do not know what the stock combustion chamber size is on 318 heads, so I wanted to check with some other members here to see if you guys had any additional information. I'd like to help him out with good deal on some heads, but I don't want to sell him parts that won't work with his combo.

Any feedback would be appreciated.
Thanks all.
