273 302 318 340 build

So got a call from machinist and crank was done being polished. I figured I would take one of the X heads he redid for me 25 years ago. He said looks good to go. All stock. Gonna diy port them when the time comes. Good to know I can go with stock adjustable valve train. While he had the crank I asked him to check for pilot bushing as this engine will ultimately be in my 69 once its done and its a 4spd car.
$20 for bushing installed. ..no brainer.
While I was in town I swung by one of Dads fellow coworkers place as he had a super sturdy cart he offered to me. Came in handy to put the 70 318 on. Even a fold up/down shelf on it.
I did my 273 heads with diy porting and cleanup. im assuming same technique? Stupid question but is there a difference 273 vs 340 heads?

Cant wait ti get started! Ultimately I would like to dress it up the same as itis now. Kinda wolf in sheeps clothing theme. I think Dad would be good with this.
He woulda loved putting this together.
Thanks all
