i am considering getting a edelbrock tpi base intake high flo manifold for my 350 tpi iroc,but i was told i should go with the tpis high flo intake manifold,who do u guys think i should go with,and if i do purchase any one of them do u think i should take them to the machine shop and get them ported more,cost isnt a problem because my buddy owns a shop like 2 blocks away

 

This is the exhaust section, youll likely get better answers in the tech general engine section. I don't know anything about tpi, but what could porting hurt?

 

I think you should ditch the TPI and get a carb or HSR.
