Default 94 Formula

Hi all, i have a 94 formula i've been screwing with for a little while now. When i bought it it looked like it just needed a crank hub from being installed incorrectly. Replaced the hub, water pump, opti, spark plugs, and coil. Tried to drive it to town to get inspected and found it needed head gaskets. Pulled the heads had them resurfaced figured while I was there might as well go ahead and install headers so put some speed engineering long tubes on and found it had some crane 1.5 roller rockers and tfs push rods installed. Deleted EGR and smog. Put everything back together and found some valves leaking so the heads came off again. decided screw it this time gonna put a cam in since having to take everything back apart again lapped the valves put everything back together again and was running halfway decent. Downloaded some tuning programs but never could get it right and seemed to have excessive blowby. Got frustrated with it enough that about a month and a half ago pulled the engine to rebuild it. Found two pistons with ring lands toast. Currently have a scat 9000 crank scat forged rods and wiseco forged pistons. Lunati springs and 1.6 roller rockers. Was going to home port my heads and see about getting some ported by Lloyd at a later date. Did tons of reading on porting by Vizard and every post i could find from Lloyd. Just finished one head and while I'm confident I've made at least a small improvement I've decided that after I get machine work on the block done I'm going to buy some trick flow heads. Currently looking at the 21 degree heads. My compression will be a little high I'll possibly have to run a little higher octane than 93. I've been looking at torco accelerator to raise the octane just add at every fill up. Also looking at trying to put a 4L80e behind it using jakes manual control box
