you used plastic lim gaskets...replace with metal ones. it looks blown out.
you might have put that there but it also could have happened from sitting, cant be a head gasket, no way for it to push it on top of the valve, unless the head is cracked.

Yeah when I saw the plastic gaskets I suddenly remembered installing them, thinking I'd have got rid of the car by now. I originally had metal ones that I installed when I first got the car, but a month later I stuck the blower on and used plastic.
I'm pulling the heads now. That loose valve stem I couldn't let slide. So I'll check them over and get a quote to install bronze guides if needed. Perhaps a couple upgrades. But who knows, I might find a toasted piston.
How was the seat of the pants experience when you installed rockers?
I might go that route. I'm thinking of pulling the engine now. I have to sooner than later do the oil pan gasket, and possibly the rear cover gasket. If I decide to, it's gonna be a long project. Daughter goes in Tuesday for braces, so my mod funds are gonna dry up for awhile. But if I do cam I need to consider a tranny rebuild. Crap, what have I gotten myself into. I'm almost hoping I find a melted piston...
You found the modding rabbit hole, lol. I started down that road with my GPGT and then reality set in and I made a plan to mod it and am sticking to it. I know what needs to be bought/upgraded and the $$ it will take and that's where it stops. Once it's together and running good I'll let it ride and enjoy it for what it is.
All that matters is that I enjoy it when it's done
Valve wiggle wiggle - YouTube
Short vid showing how much movement is in the valves. Head gasket was fine. I know that the chances of it failing were slim, but I had to know. Obviously I screwed up the valve seal install. If I use this head I'll replace all of them. Wonder what the tolerance is for valve wiggle.
I think you should take the heads to the machine shop and get a multi angle valve job done. and while they are there, get them machined so you can run an xpz cam.
Ya, I agree. Gonna pull the other head and take them to the machine shop. I could pick up another set at the yard, but I've got so much time and money in these I gotta find out if they are worth fixing. Are there gains to be had with bigger valves, without rocker/cam?
With all the slop in them, I'm surprised they haven't touched.
Alright, cool. So if the heads check out and don't brake the bank, I'm thinking VS cam (because it's much cheaper since I don't have to do chain, big springs, oil pump cover etc) and I'll dial it in on the Gen 3. Then later I can do Gen V when I find a nice one.
The VS cam is nice. not too lopey, but really good midrange torque. On a goodsetup (VS, 3" pulley, intercooled, headers, and tune) you'll put down 300 whp and run low 13's high 12's all day long.
you can get a good used gen 5 for like 125 bucks off LKQOnline I would also do a northstar throttle body and LQ4 maf at the same time.
Ching ching cha ching.. Will the madness ever end?

gen 5 swap ran me about 400 bucks in all, 117 shipped for the blower, 30 for a used N*, 50 for a maf, n* to gen 5 adapter plate and pig tail 130, 15-20 iirc for the blower bolts for the ic and gen 5, then like 90 for the 4 inch intake tube couplers and new filter.
then i sold my gen 3 belt wrap for 125 and bought one for the gen 5 for 150. so 25 more lol it adds up fast.
