Default 93 and up IH porting

Ported the top of these, have not touched the lower half yet, as you can see injector boss is much smaller, however as its not o-ringed on the primary cannot eliminate the boss...top portion very restrictive, they left alot of performance on the table in the first inch of the IH

Are these for a Customer or one of your own?

I believe someone is sending me a set to port, if they want their originals I will do those, but these are a set I got with a car I purchased, were sitting on the shelf so I thought I would get a head start.
