I just bought a set of TC 05 heads off ebay cheap that look great with low miles. I was looking at buying a set of SE performance springs good to .650 lift off ebay when I noticed it said for 99-04 TC. The question is does 05 TC heads take a different part number spring packs than the 99-04 heads?? I know there is a different valve angle and they used lighter valves starting 05.
