Outer Limits 4x4 Board

I was looking at a 2H head today and was amazed at the small size of the valves in relation t a petrol engine . Any body ever open up the valve sises on a 2H? The ports look reasonable size , but the valves are miniscule.
I got the flame suit on for the " why bother" crowd but I am just curious. Someone out there must have done something like this.

not nearly as interesting as i was hoping after reading the topic... not really sure what i was expecting but...

I thought I'd get a lot of those " why bother" answers. I just feel there is a lot of potential there , thats all.
Apart from what we burn to make power, the basics shouldn't change. Let it breathe !

I did it to mine and ran stacks of boost, modified pistons, it went well...

it cant hurt to give it a try... well it can hurt... but if it comes off it may well be worth it.
