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

Re: 93 and up IH porting
Are these for a Customer or one of your own?

Re: 93 and up IH porting
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.

Re: 93 and up IH porting
Lee,
I'm thinking Jeff may want his 93-95 IHs ported.

Re: 93 and up IH porting
Everyone says they are too thin in the walls, I am not sure I agree...and the floors appear thicker than the 90-92....these are pretty damn big
