'95 LT1 Head Gasket
'95 LT1 Head Gasket Okay so the head gaskets are blown on my '95 Z28 6spd. Car has 155k but I picked it up for 900 bucks. I'm 19 and don't really have much experience doing this kind of engine work on a car, but we all got to start somewhere right? Been looking around and talking to mechanics even though I'm going to do this myself. Cheapest I've seen for a full top end gasket kit is 170 for Fel Pros. Anything better out there? Also bunch of mechanics have been telling me I'll need to replace the head studs too? I'm thinking their just bullshitting me but any truth to this? My Dad will be helping me but his knowledge is mostly SBC's and BBC's so I'm just doing alittle research. And the search feature is FUBAR. any help is appreciated. Also the car just had the radiator, oil cooler, alternator and a few other things replaced. I'd say it was a good deal even with the blown head gaskets.
Here's my '95 Z28 6spd hardtop.

are you planning on replacing gaskets throughout the motor or just replacing the head/intake/exhaust gaskets? are you doing the work while the motor is in the car or are you pulling it out?
Yeah they should be stock, I'll have to check since I know the previous owner did do something with the heads which led to the gaskets being blown. How will I know if there stock vs aftermarket?

i want to give you some advise...
your dad might consider this since he knows a little about engines, and pertaining to the amount of mileage on your car..
when you blow a head gasket generally anti-freeze will get in the oil and the anti-freeze gets to the main bearings and can damage them..
if the previous owner drove the car for a length of time with a blown head gasket chances are you might need main bearings also, plus it might save you time later on..
would suck to fix the head gaskets just to have to go back in within a month and put main bearings in it.. antifreeze will wipe main bearings, seen it more than once.
i think you would be money and time ahead pulling the engine and just doing a budget rebuild now.
just my opinion..
good luck on whatever you guys decide.

From what I was told the car wasn't driven with the blown head gaskets and when we checked the oil there was no sign of coolant/water in the crank case. Oil was still nice and clean no milky residue etc. When we tear it down tomorrow we will find out for sure.

Verdad Gallardo Thank you, sorry for the noob questions..should I buy stock bolts or aftermarket studs even though I'm not going for performance?
Stock TTY can be found online for 25-30 dollars, ARP head bolts are around 60 but I think it is worth the extra money just in case the heads have to come back off for one reason or another they can be reused
I can't seem to find any Gen 2 stud kits?
Nvm these should work.

I just used a fel-pro set on my 1995 Z28 and it didn't have any issues. When my head gasket blew the water jacket on the rear most cylinder on the drivers side cracked and sucked anti-freeze into that cylinder. I never had issues with oil and water mixing. Just lost lots of coolant. That cylinder was nice and clean when the heads came off.
So I just doing a stock rebuilt on the car. Replaced intake, valve cover and head gaskets. Bought stock head bolts and rocker nuts which needed replacing.
Now my question is before I put it all back together what heads would have came stock on a '95 Z28? I have a chance to buy a set of heads off of a LT1 Corvette. Casting number is 10207648, now would these be worth it for 100 bucks? There complete minus rockers, could I just use my stock rockers?
