When I use the correct 1" reach plugs in the Ecotec in the 600 the piston closes up the plug gap down to almost 0".
I have been using 3/4" reach plugs for a while but didn't like the partial shrouding of the plug.
I tried indexing washers but couldn't get enough clearance with the tapered spacers.
The first pic below shows a stock plug, the modified one, and the result of the piston contact.
2nd pic is the 1" plugs as purchased and modified for installation. ( The new plug in the pic isn't "bent", it's just lens distortion.
