Ok Guys i have 96 ek hatch with 97 gsr swap. bone stock with short ram intake dyno tuned with obd 1 p72 gsr ecu chipped with crome pro. Im driving today at night and i just replaced my headgasket, all seals on head one month ago by a shop. I m driving on freeway normally and im going steady speed at 4th gear around 3k and i decide to downshift to third to gun it and hit vtec at 5k and all of sudden cel pops on my car bogs bogs when i hit the gas. ******* weird. So i shut the engine off and start it back up and cel gone and drives normal again. Until later on i do the same thing and gun it past 4k not even hitting 6k car lost power or shut offs. I checked my motor and headgasket is leaking again, and the back of the head leaking oil down to the block. Damn what could be wrong??? Im bringing it back to shop tomorrow, maybe bad seals??? Oh I had the shop reuse head studs and i didnt get it the head port and polish, which he recommend. I check oil level on dipstick, it looks fine, but maybe im blind because its dark outside. Sorry guys, im just depressed, it happen out of nowhere. Now it drives normal, no cel. Should i get arp head studs and bring the head to machine shop tomorrow when the shop redoes all the seals including head gaskets no charge??

 

Will i notice power difference with bringing the head to machine shop?? to port n polish?? I can see oil coming from the hole on the head behind?? Next to timing belt cover the hole below the back of the head? Could it be bad seals??
