Any comments regarding the Snyder's 5.5:1 head to replace my stock version? I have read a number of comments on this site recommending 6.1:1 or even 6.5:1 but also several claiming that they add significant stress to rods, and bearings. There seems to be a level of disagreement regarding that issue and I would rather err on the side of less stress and slightly less compression while still improving performance so that I can make it up the steep hills in my area in 3rd gear. My concern is a few posts stating that there have been machining issues with the 5.5:1 heads. Are they all made by one manufacturer? Is the one from Snyder's particularly problematic? Overseas shipping and customs duties makes returning defective parts expensive. I will appreciate any input.
