Nothing really harmful there especially since you are lower compression with the HG. Get all the services you mentioned. Deck, pressure test, hot tank etc. Do it once, do it right.

Matt, will those fit a 6 bolt? are all of them the same? Ive been meaning to get the upgraded lifters too. Im getting nasty lifter tick and I think its part of my phantom knock issue too. If I just order 16 of these Im good to go??

Yep. 16 of the 3g lifters in any 4G63 will take that tick and make it go away. All they are are the exact same lifters as ours, but with larger oil passages that help get the head lubricated faster. Exact same part, different hole size.
