I guess I could try my hand at porting with these 317 heads. I have to try to get the broken bolts out of one of them first. Do these blocks have an area of concern for cracking etc? I just don't see a reason to replace this one unless catastrophic damage has occurred. I can't find any real damage yet. Maybe there is a cracked piston under that other head. Maybe three broken exhaust bolts gave the computer bad readings and made this thing run like shot. I can only see a possible exhaust leak on one of the exhaust ports on the head but not the exhaust manifold. So maybe port the heads, big cam, hone the cylinders, new rings/ maybe forged pistons, new ARP bolts throughout. That should give me a real base to start with. Run that 5.7 hard knowing I have a good backup...
