[QUOTE="kyle1, post: 831207, member: 16294"] i really wish people would stop spreading down that hearsay BS around...a 20R head doesn't crank up your compression. here's my advise for doing this job. clean, clean clean! you want the deck of the block and the underside of the head as clean as you can get. i like using a rigid blade scraper(sears sells them for about $10, looks like a long handled chisel) as it won't distort like a razor blade scraper and cut chunks out of the head. once all the gasket gunk is off, i use brake cleaner and a non abrasive scotchbrite pad to make sure it's all gone. if the head looks iffy at all, get it resurfaced, just enough to clean it up. don't ever use a felpro head gasket on these engines, you'll be sorry. i only use the graphite gaskets with a steel plate on the head side -- engnbldr, toyota, and napa sell them. i wouldn't hesitate to use felpro's other gaskets, though. i don't bother retorquing after running it, the only head gasket i've ever lost on one of these engines was from having a warped head that should have been decked. i usually go in a few steps on the head bolts, 20lbs, 40, 45, 50, then final torque. i go inside and have lunch or something, let it all settle and then hit all the bolts with the final torque setting. if none of them move you're good to go, otherwise let it sit a little while longer and do it again.
