99 forester. Ej25 sohc knocking due to oil starvation. Bearing journals were too small for any local shops to turn the crank so I found a very low milage (64,000 MI on odometer) short block from an 08 forester ej25 sohc. All was going well till i got the timing belt on (much tighter than on any videos I could find) tried to turn engine over and found raised portion of piston between intake valves contacts head. Gaskets were for 99 and compressed thickness .054 in. #1 is there a simple fix for this or do I need to take the die grinder to the lip on the head (if so how much clearance is required)? #2 is there a difference in the blocks that I am missing making the timing belt ridiculously tight without pulling the pin? I have done timing belts on dozens of vehicles (this is my first Subaru) and am positive this is too tight. (I did swap the crank gear from the 99 onto the 08 engine because the backing plate for the sensor was different.
