​​​​​Is there any drawbacks on this porting? Was going for a aggressive street port. Using for a single turbo flex fuel e85/pump gas 94 FD with haltech elite series 2000 radium fuel lines 1300 ID primaries four 2600ID with xcessive LIM built2apex surge tank bw sxe372 with two 45 wastegates v mount koyo radiator

 

the streetport portions look just fine. but why not just finish cutting the bridges though?

i've seen one other person here do a port job like that, but it was a long time ago, so i don't remember much in terms of setup or results (if there were any posted at all).

 

Cheeseports have been discussed many many times over the years, and are certainly thought of as being 'hacky'. Just finish the bridge.

You can't get any extra flow out of those drill holes, so it's essentially pointless as you won't get any power/response benefits from it (I'd argue that the small holes actually create turbulence which would hurt performance of the engine). They say you get the bridge idle sound with none of the drawbacks....but I disagree. The one I heard had some chop, yes...but something was very off in the sound. It didn't sound healthy.
