Brief Description:  New head bolt installation

More progress! I managed to get all 12 long head bolts out without tearing anything up, what a relief!! I used a heat gun and penetration oil and repeated heated and soaked each bolt over several days until they each released. Weird fact: the left side was very difficult to remove requiring several days and much patience. The entire right side unscrewed easily and cleanly in about ten minutes. No idea why... Then I had to wait for the new bolts to come in from SPA.

Once my new head bolts came in, per SPA's recommendations, I cleaned the holes in the block and installed the new head bolts on the right side. The threads were generously coated with Loctite 620 which should bond the bolts into the block. 10 pounds of torque has been applied to each bolt while allowing ample time for the loctite to cure. The left side will be next. You can see the new bolt in the middle with the stripped bolt on the left and a uneven, shorter bolt on the right. The new bolt has much more thread to work with. Stay tuned for more progress... I just might make AirAdventure 2018 yet!
