The 205 cc Mongoose street LS1 heads should work well. Swap the camshaft while you're at it. If you call AFR, they can suggest a cam that will work well with their heads. A head and cam change along with what you've already done should put you close to Lightning territory. Also, if and when you do the head / cam swap, you'll be best suited to have your ecm custom programmed by a shop that's familiar with LS1 edit, etc. Hand held programmers don't cut it once you've done som emajor mods.
