Vette(s): 1981, Black/Black, Engine bumped to about 400HP.Ext/int mostly stock.

I seem to remember from a couple years back someone posting a list of all fasteners on a Chevy small block and whether it should receive RTV, thread locker or oil. However, I cannot find that post. Can anyone point me to such a list?
Thanks!

Click on to this link...........it might help you. http://www.smallparts.com/products/descriptions/al.cfm In the past, I would contact Loctite hotline 1-800-loctite (1-800-562-8483). They would answer all of my technical questions.......VERY NICE TO DEAL WITH. Also get a Loctite catalog. It answers a lot of questions. They are handed out at Summit Racing. Good luck with your project. corvette440hp2008-01-18 09:31:52

I use Loctite 242 on the suspension and engine. Permitex also makes a line of thread lock. I spec medium strength thread lock on the diesel engine packages I design mainly because of high vibrations. Bolts generally don't come loose if properly torqued but its cheap insurance to use a thread lock. Nothen but the best for my baby

I am reading up on change the cylinder heads and cam. Often it is mentioned to use sealant on head bolts to keep water and oil from leaking. I thought that is why you use a head gasket, but no you need to use sealant.

Can you just use thread lock instead?
