not that bad. ~$450 for it all. thatll be the next purchase.

those rocker arm rods are on there pretty good. was getting late and raining so i didnt get a breaker bar on em. i wanna see which ones are worn/how bad. with those off the springs and pushrods will just come right out?
 






Pushrods yes springs no.heads have to come off to get them out
 






more yucky. EVERYTHING is covered in gook, even the bolts

Dang.. Those rockers CAN'T have more than 200k on them (or however much you think you have).

They look brand new compared to mine at 170k :p:
 






im at atleast 260k. possibly 360k. so far its looking like he did have a rebuild 36k ago, but went very cheap on parts, 90tms. and neglected the hell out of it and then let it sit for a couple years
im guessing my ticking was the pushrods? being the rockers dont look that bad
 






eeehhh I'd wait till you get to your lifters and check them out. You really don't have too much abnormal wear there IMO.
 


















What those rockers are worn like crazy.look how deep the valve worn into it.Brandons only had like two worn ones,i think all those paint fumes are get to him!!hahahahha what are you trying to degrease?
 






high on high visability green! lol i couldnt tell i hadnt looked at my new ones since i got them, so i couldnt reemember.
well i took apart the rocker assemblies. i want to clean up all the gook on the rods/springs/other part. and clean other various parts down the road when i get to them.
once i clean them should i rub a little oil on the rod/inside new rockers for lube?


got an answer on the heads. he said 90tm/93tm (ill add a message when paying make sure they say 93tm just incase), and he said $5 off 2nd heads shipping for buying two.
so i think that should be $273 total
 






Lube is allways your friend!! Thats good man thats a pretty good deal.90/93 are they same head when it comes to aftermarket,as long as it doesnt say 95tm.you should be happy with those heads
 












Nope go get some assembly or valve train lube from advance.its normally red and super sticky and slick.its in a little bottle
 






























I am have just as much fun (NOT) getting my exhaust bolts off. I ended up breaking 1 of them and drilling the other off like you are doing. I removed the plastic liner and way more room to get at them. Both on the pass side exhaust to exhaust manifold. I found that there is a product called studfix that you dont have to drill out the remaining stud in the exhaust manifold. another post on this side mentioned it.
