I have an ej25d block. I have dual port heads from a 1st gen legacy, and a 1st gen intake to swap components to.
My current car 96 legacy brighton 2.2 single port heads.
I was going to use dual port heads on the ej25 block, but if there is an advantage to using single port heads, i can consider them,but at the expense of a functioning engine for parts.
I read that the single port head has bigger valves. Is there an advantage with single port heads in regards to valves or cam options vs dual ports?
