Re: Steel IH Gaskets & Primary Port is 38mm
5 ft lbs of torque is a nice pick up

Re: Steel IH Gaskets & Primary Port is 38mm w/ dyno runs
The 95. Surprising increase for port work, headers, exhaust and chip. I would like to keep the 92 as stock looking as possible. My plan for that car is top end porting, and may just remove the resonators and install a cross pipe in place of it. I read on Marc's site that these are a major flow restriction in the stock exhaust system in the 90 through 92 Z's and install a chip.

Re: Steel IH Gaskets & Primary Port is 38mm
Great thread Im going to sit and read through it all from the start to see if I missed anything =D>
I too have been debating on going at the heads to match the port work but Im not brave enough to get in there.. yet. Im about to install mine tomorrow I spent the entire day cleaning gasket surfaces and just finished cleaning and replacing my o rings as well. If I may ask did you use any gasket sealant or high temp rtv etc on the gaskets ? I was wondering if maybe I should line them up with a tiny bit just to be sure they seal. Great numbers btw !! |

When it comes to sealant everybody has an opinion. Because the injector housing to head gasket is leak prone, I used a high tack Permatex product around the coolant and PCV passages. Item # 765-1221. Kinda messy, use thin coats. I have also seen #80019 recommended. The first one is made for NAPA, I believe they both are similar in function and application. I used "dabs" of it for the intake to locate the gaskets because my gaskets had to be hand trimmed to fit and they needed to be exactly located, no room for error. If you don't need to use it for the plenum, I wouldn't use it. If you still have coolant passages in the plenum, you may wan to use around those only. Take special care torquing all bolts. Use a torque wrench and clean all bolts and bolt holes the best that you can. I use a an ultrasonic jewelery cleaner with paint thinner or Simply Green. I used medium strength blue thread locker on bolts. Jerry's gaskets has a great "thicker" Loctite product that worked very well. Also, keep a spare set of gaskets handy, never know when you may need to pull the plenum again.
