Hey John, my dad mentioned something the other day, we were talking about it more. And he said it *might* be the wrist pin on the piston. Im not sure, but, if you replace those heads, and it keeps making the noise, that would be the first thing I would check next.
BTW, dont change just one head, while you got all the TPI/intake stuff off, put both of em on there. You got a valve spring compressor to do the seals right? If not, swing by a parts store, and pick one up, your gasket kit should have came with the seals, mine did when I put the L98s on.
Let us know what happens!

1988 Pontiac Trans Am WS6 - 305 TPI, 700R4, 3.23 Posi, Digital Dash, Leather Seats, Maui Blue with Silver GFX, T-tops, Tinted Glass, Gutted MAF, TB Coolant Bypass, K&N Cone Filter, Hi Flo Cat, 3" exhaust from Y-pipe back, MSD Super Coil, Accel 8mm wires, L98 Aluminum Heads, Ported and Polished Plenum, Siamesed Intake, Aluminum Driveshaft, Edelbrock 3 point Strut Tower Brace
I was figuring On doing them both. It just pisses me off that I had it all the way down to just having to take off the heads and I didn't do it. I doubt it's a wrist pin 'cause it only does it when #6 intake closes to rest against the head. But I guess we'll find out.

well well well, The lifters on #6 were toast. the roller balls were flat on one and gone on the other, and the body of the lifters were screwed up. the exhaust lifter was the worst half the lifter was gone. Anyway I broke my exhaust manifold on the passenger side so now I need to find another one. SO I guess junkyard time.

How bad is it broken, and what part? Howd you manage that one John?
Good to know you got it figured out! See, I told you that you got a damn good deal on that thing!
Yeah, you should see those things. Those roller bearings are toast. I was over there today watching John work on his IROC. He was too slow though to get it all back together and running before I had to leave Got out my digital camera to take some pics to show ya'll, but the batteries were dead. What can I tell you... Life sucks sometimes, hehe. BTW, Rollerball was my favorite skating movie when I was a kid, but ever since I saw Boogie Nights I'd have to say that is my favorite roller skating movie now.
My cam is a roller cam so it has roller lifters. Basically the lifters have little balls ont he bottom that roll along the cam. Those balls were toast. anyway all back together sounds allright but there's sitll a bit of an exhaust leak. a neighbor guy happened to have the EXACT same exhaust manifold I was looking for. I'm gunna take it to the muffler shop and have 'em mate it up right. I'm sick of crawling udner hte car. It'll run now so I can take it to the shop.
Actually, it's a cylindrical roller set on needle bearings. It rolls over the profile of the cam as the cam rotates. A ball would do the same thing but allow rotation in any direction and it would have a very small contact patch resulting in cams that groove quickly because of the high pressure at the contact point. The cylindrical shape of the roller reduces the pressure on the cam by increasing the contact patch. Sorry, I just had to clarify. hehe.
