Mike it may be just me but I would get new heads. Fixing what you have can lead to future problems. Sleeveing and threading aluminum just sounds weak. I'm not saying it can't be done nor done correctly for a normally assperated car. But blown down, with the numbers your puttung down, well I don't think it will last long enough to say it was worth the time, effort, and money. Lets look at it from a different view. The bad head has to come off for repair anyway. Jezz it's out of the way, why not replace that and do the other side with upgraded heads. New tune and your done. With new better breathing heads vs broke, weakened, and repaired old. Just me I'm sure I've stirred the pot on this but I would want longivity as well as performance.
