I really don’t know where to post this question. Ok you guys I ran into a pretty big problem just a couple of days ago. I bought some after market heads, they are the Pro Toplightning part number 223400000A with an intake runner of 200cc. So I took my heads to a shop to get them built and I also took my TPI intake in to get port matched. Well they did build my heads but they told me that I could not use the TPI intake with my heads. This is not a big deal; I was just going to get a LT1 intake for it. So I wrote John at ltintake.com and he told me that the LT1 intake would not fit the ports of my new heads just like the TPI intake. My question to you guys is do any of you know of a good fuel injected induction system that I can use on my new heads that offer good flow?? Or will I have to convert to a Carburetor? Please I really need your help guys!!!!

 

It's a standard Chevy pattern intake port setup, not sure why people are saying the ports won't match.

However, to get anything out of them, I'd think you'd need a high-flow intake such as a Miniram or Stealthram.
