From what i understand oil pan used to do porting at the site here, but since his location now says japan, who knows

[oil pan 4]

I have been living here in japan for the last 23 months. I went home for 4 weeks this last summer and mostly worked on my Z28.
To get started look at as many things as you can. Look at bad 305 TBI truck moter castings and find out where there bad, Learn the bad heads and what makes them bad. Then look at good heads like LT1 and vortecs and ok heads like the 58cc 5.0L IROC heads like I have on my Z28 compair them to the bad heads. Then Check out ported versions of each if you can and see what people changed to make them flow more.
The push rods heads like in our v6 and the SBC are a lot alike by design.
Then if you can get a look at aftermarket heads and compair them all, go to some thing like a swap meet and look at heads.

well what i'm going to do is buy the intake and exhaust manifold gaskets, slap em where they go and mark where the gaskets have them holes. then that way i know where to port match em to. that sound good?

that will work for the first few centameters of the ports before the port starts changing shape
