I would not be so quick to dismiss the stock heads, I see it as two choices, port the stockers or buy a set of trickflows from someone like Advanced Induction and have them ported before you ever see them. Using them as cast would be a mistake.

After rereading your post looks like you already have the cobbled together shortblock???
The full Compstar package is better than Eagle stuff and the price can not be beat for the quality.
If the shortblock is together we need specs because it may dictate your head choice.

Trickflows are a good choice with boost because the bigger chamber will lower the compression some which will allow you to run more boost.

Depends on the pistons, if the pistons already have a big dish then the 64cc chamber might be too big.

Look at the AFR heads if you can get your hands on some. Get those ported by a reputable company or person and get them to match them and a cam to your setup. You need to decide what kind of FI you're going to do and how much before you can go much further.
