Hey guys, I am ready to put my head on after getting a valve unstuck but am running into a problem. When chasing the threads my 7/16-14 tap is VERY tight after about 4-5 threads, to the point I stopped and didn't go any further because it felt like I would be removing steel rather than rust/debris. Is 7/16-14 the right size? Am I doing something wrong? I'm using 3 in 1 oil and drenching the threads and tap beforehand, and started, then backed off, repeat, but can't get further than the first four or five threads.
Also, I bought Pioneer bolts, but noticed they have less threading than the stock bolts--did anyone else notice this when they did theirs or did Pioneer change something? I only wonder because it looks like it would be real close in terms of having enough thread to get proper torque specs. Thanks all.
