Hey fella's i need some help.. I have a set of 243 2.5 ported heads.. I noticed my car had a dead spot at partial throttle so i dont some looking around and trouble shooting and found that the #6 plug was loose.. So i tried to tighten it and it wouldn't... So i tore the head off and put a Helicoil in.. Put the head back on and it worked long enough for me to get about 100 miles on it and a dyno tune.. then a week or so later it started doing it again.. I done a compression check and found i still have a leak in that cylinder.. I already dont the Helicoil so is their another option to fixing my problem.. I called a few machine shops and they didn't sound to confident they could fix it... Any Help would be appreciated!

Impossible to answer until we know what actually needs fixing

Anything can be fixed but cost effective maybe not. Post a few pics too.
