I figure I would use a long scribe and mark the heads while the intake is still on the head.

Reference: Jerry's Gaskets are port enlarged to 36.5mm and precision die cut to dimensions from original engine drawings, so they make an ideal template to work from. They retain the bifurcation between the primary & secondary ports for stock applications.

You would benefit in the long run by using a set of correct gaskets as a reference for both the injector housing and cylinder head ports to match them up. Then, you can use a new set of gaskets without having to trim to match. At this point, it's not known if the injector ports are correctly located. I have seen significant core shift in early housings. I wouldn't recommend matching your Dunn heads to a set of injector housing that are not ported correctly.

BTW, you also have Aaron Scott, South Georgia Corvettes, in Thomasville, GA. He is closer to you and very well versed in the LT5.
