Im tall (6'7", with 82.5 wingspan) and want to get into archery so when i came across a deal on a 27in kinetic sovren riser i jumped on it (hooray). I also picked up some used limbs - long galaxy bronze star 30lb. Id like to start with barebow target shooting.

I got a 72in string in the mail today and strung the bow, but i immediately learned i have two issues:

1. im drawing these limbs so far back the last inch or two is quite difficult (stacking?). Using a scale it seems Im pulling these limbs to 38 lbs. Obviously i need lower poundage limbs. Any recommendations on affordable limbs that are less prone to stacking when drawn very far back? XL limbs are out of my price range. Also can i assume i should buy the lowest pound possible (20lb) since ill be adding ~8lbs at my draw length?
2. The wingspan ÷2.5 rule of thumb says i have a 33" draw. I used a wooden dowel rod to measure where it felt comfortable to draw to and it was closer to 34". Id like the arrow to be 35" or so but almost all of them stop at 32" long. I found a few 34" shafts on Lancaster but the tip will be right on my arrow rest. Are there any longer options out there, or will 34 be enough? Or are there any tricks like longer nocks or tips i can use to squeeze out another inch?

If you made it this far, thank you! I appreciate the help

Ive read one should be mindful of head bolt removal order to avoild warping or cracking heads. Im tearing down my first engine (an olds 455) and all my service manual has to say is "remove head bolts". Does order not matter for this particular engine? Or is there a rule of thumb I can go by like start from one side or just reverse the assembly bolt pattern? Thanks
