273 302 318 340 build

I am not against doing diy port work on the heads. I just seem to be going down the same road with the 318 (stock low comp pistons)

Makes me almost contemplate putting Kanter commando pistons in the 273. I think landed to me about $600 canadian. Then bearings gaskets and now call it close to a grand.

I think the bigger valves are only worth it if you are seriously porting the heads. Not really necessary for what you want, I think.
