Thanks Guys. Far as welding and grinding I have had many type 1 engines with the intakes welded and ground to match the head ports. The 2276 I just sold was an example of the intakes being ported so large they had to have the extra material welded on both the head and the intakes. These were sold this way by CB. I guess I didn't word my question well. I was mostly wondering why venders are selling ported heads and not the intakes that are match ported? The issue with the type 4 heads and manifolds is the lack of sealing area if the manifolds are ground out to match the size of the cylinder head ports. I was looking for others that have actually port matched their type 4 intake manifolds.
Gordon , it sounds like you are talking about a type 1 engine, is that correct? Below are pics of the heads and intakes on the 2276 type 1 engine I just sold. They were extensively ported. You can't see it the pics of the intake manifolds but they are welded up a ton. I guess others are doing this themselves for the type 4 applications.
