Save yourself mate. Don't open it up yet. Just get it in, aftermarket ecu with intake, headers & zorst & enjoy it for years without hassle.
If you wanted to do all that, might aswell have done a high comp original Gen2 with cams, ECU & E85. The Beams is a great reliable factory motor, don't fix what isn't broke. Leaves too much room for error.
