To see if I'm missing anything big or need to make changes.

Plan is:

I've got my 241's off getting decked and 3-angled. Decking is in this case .002 - .004 (worst case). I've currently got Patriot Gold Extremes for springs and the machinist says the seat pressure on them is at 133-136 ft/lbs right now. I'm switching from my stock rockers (1.7:1) to a set of Comp Cams Ultra Golds 1.82s (19025-16). The cam is a Lunati 55008 with advertised .595/.595 237/243. . . So I mic'd the intakes and exhausts. Mine mics at .600/.601. Now before you say a 1.82 on that exhaust will be horrendous, I've got a plan remember. . .

I've got it potentially working that a friend gets a set of 1.72 Comp Cam Ultra Golds (19024-16) and we swap 8 for 8 giving us both 1.82 intake ratios and 1.72 exhaust ratios (giving me a .635/.608 - not too far off from the MS4 .649/.609 239/242 #'s). Anyway, I'm checking my pushrods lengths for appropriate swipe on the valve stem. . . I'm clay-checking the clearances on 2 separate cylinders. . .I'm putting in new gaskets, new bolts and everything is cleaned nicely. . .removing the coil packs (relocating). . . adding new valve covers with larger clearance (not needed but damn they look GOOD!!!). . . re-tuning the car. . . saving money for new rear end axles (have a Moser M9 nearly built). . . considering relocating the battery to the back in the next few months. . .

Besides pics to brag, what am I missing discussing or planning for?

Thanks,

D

Oh by the way, I'm also using new valve seals, new GM graphite type stock head gaskets (I believe .040"), stock (new) GM head bolt set. . .

Why the push for the big intake lift? Nice covers.

big lift makes big breathing available. . .

thanks on the valve cover like got the heads back a bit ago...
rockers and valve covers look good w/them

Heads still need some cleaning/polishing to make purdy...

ive used those covers before. Relatively cheap and affordable. And seal well. Just strange finding the "tight"point

i don't think the added lift gets you much with 241 heads.

just curious, why you goin with the graphite head gaskets? i went with the mls gaskets and they have been great so far.

my thinking was that it lasted nearly 100K miles w/stock gaskets, so I cheaped out and decided to go w/same. As it turns out though, I've cancelled the graphites and have the mls en route. Good question.

anyone else? Once the gaskets show, I'm looking to clean the last bits and put it back together!!!
