I've used both bolts but I'm not making silly power. The only way to accurately determine if the bolts are re-usable is to use a stretch gauge. I know of people that have re-used the bolts and haven't had any issues. I don't like digging in to the engine, so I usually buy the bolts from MSM or ARP.
Gaskets seem to be a matter of brand loyalty. I prefer Felpro or whatever the OEM spec is. Again, I've heard of people using the ebay gaskets w/o any issues.

how much worse would say this one be http://cgi.ebay.com/ebaymotors/88-89...Q5fAccessories
compared to a felpro set. running about 18 pounds on a vj-14 vj-9 hybrid should i be alright? and how much more could i throw at it?

just reading the manual it says check for movement in the HLA by pushing it during disassembly. right after it says if the HLA moves replace the HLA. what? shouldnt it be able to move, thats why there is a spring in there right? if it does not move there will be a gap between the cam and that would end up causing the ticking?? why does it say if it moves replace it? very confusing, as far as the head bolts i dont know if i want to spend a hundo on new ones...

If you are able to compress them by hand, you can either replace them ($$$) or try your luck and clean them. The theory is that the HLAs operate like a one-way check valve, with very tight tolerances. The tolerances will / should keep the oil trapped and the hla pressurized.

It's been a long time since I've had to do mine (1995, If I recall), but I remember disassembling them, cleaning them in some solvent (I actually think I soaked them in an ultrasonic tank), re-assembling them, then soaking them in a coffee can full of fresh oil. I took each one, submerged in the oil, and squeezed them until they purged the air / solvent. I recall them being stiff after. I installed them immediately and they ticked for a little while, but after a few short drives to work, they quieted down.
Give that a shot; if they are still noisy after a while (maybe change to a different weight of oil?) then you might need to source some lifters from Kia, or try your luck at a junkyard: Miata, Capri, etc. etc. Maybe someone here on this forum has some to sell. I know that there's a few people parting out some GTXs on the yahoo forum at the moment.
Good Luck.Last edited by BFMRGTX; 05-19-2010, 05:27 PM.

i already took them apart let them soak in brake clean and then lubed up all the interior with mobil 1. there just sitting on the table now though, have not been put back in yet. prob drop them in some oil before i re install... can i re use the two little caps that hold the valves and springs down? the things i had to take off to release the valve? not sure if im going to get a gakset set and even if i do i dont know if it comes with most of em.

for the HLA's, after cleaning them they will still be squishy. once installed and run in the engine for several miniutes and a quick drive they should pressurize and quiet down."See that car, in the 80's that car was deadly." Random man to his son while passing the GTX in a parking lot

For the tracer rear bench.. the colors will be off and i believe you'll have to trim the foam down a bit to get it to sit right. I'm not sure how much it would be to ship but i have a couple spares if you want one. What's wrong with yours?
