So i recently replaced the front main seal on my car and when i put the motor back together i put the timing belt on advanced one tooth (i didn't find this out until now ). i ran a few days and didn't realize it until it detonated and blew up two spark plugs (cylinders 1 and 4) running ~27psi.
had the car down at southern worthersee and just threw a new set of plugs in to get me through the weekend.
once i got the car home i did a compression test (motor was cold) and the #4 cylinder had the lowest, which the worse plug was in..
#1 - 125psi
#2 - 134psi
#3 - 108psi
#4 - 60psi
pulled the head off today and found the head gasket blown between cyl 3 and 4.. the pistons and cylinders look ok and have no marks or scratches. the valves look okay also, none look bent but i want to get the head checked out to make sure the valves seal and aren't nicked or anything. i also saw oil seeping down the valves so i'm guessing i would need new valve seals?
is there anything i overlooked that can be damaged?

so what would you guys recommend to get the most out of my setup in my head? i was looking into getting integrated's IECVA1's and revving out to 8500. should i look into an AEB head? not looking to really spend a ton.. what do i need to replace in the head while i have it apart?
