2.3L head question

[luvtruck]

Hello i am wondering what would be a better head to use for my turbo build. I have an 8 plug head from a 1990 and then i have an oval port from a 1987. I will be porting and prob putting bigger valves in. I just want to know which is better to start with.
thanks

87 should be D port not oval port. Regardless, both are better than the dual plug.
