==Intake installation== Generally speaking, using RTV on intake gaskets acts as a lubricant until it's set up; using it alone can let the gaskets slip out of position when tightened. Most gasket makers caution against using RTV, especially on the side of the gasket that has an RTV bead applied at the time of manufacture. Instead of using RTV over the entire gasket surface, use [http://3mcollision.com/3m-super-weatherstrip-and-gasket-adhesive-08002-yellow.html 3-M weatherstripping cement] or [http://www.summitracing.com/parts/EDL-9300/ Gasgacinch] on one side of the gasket to hold the gasket in place. These are able to hold a gasket in position almost immediately if applied by the directions. Nothing is needed on the other side in most cases, although a light application of RTV (following the directions for skim time) or one of the non-hardening sealers mentioned above can be used around the water crossovers on ''both'' sides of the gaskets, in conjunction with the cement. Some prefer to use [http://www.permatex.com/products/automotive/automotive_gasketing/gasket_sealants/Permatex_Super_300_Form-A-Gasket_Sealant.htm Permatex 300] or [http://www.permatex.com/products/Automotive/automotive_gasketing/gasket_sealants/auto_Permatex_Aviation_Form-A-Gasket_No_3_Sealant_a.htm Permatex Aviation] non-hardening sealers. {{Note1}} A couple cut off bolts or studs can be used to position the gasket perfectly, remove before installing the intake. RTV should be used on the ends of a Chevy intake instead of the cork or rubber seals supplied with many gasket sets. Apply a 1/4" thick bead of RTV across the seal surface at each end of the block. If using an O2 sensor be sure to use sensor safe RTV.
