So machine work should be done by next week. Was a bit more extensive than I originally wanted but at this point YOLO. Bores were at the service limit and beyond a hone so now its 30 over. Heads were shaved flat and pistons are 20 in the hole. Which gaskets should I get? I bought a whole gasket kit that includes the stock 0.051", but should I get the VR 4.100" x 0.026" gaskets? 10.5:1 vs 11.3:1 CR and 8.2:1 vs 8.78:1 DCR. 0.071" vs 0.046" for quench. I want to run 93 without issues.

Recommendation on spark plugs?

Thin gaskets. Do not go old school SBC thinking on SCR.

Stock heads, I used to run autolites, step colder than stock. I run TR6s now though.

no gasket, Copper RTV spray and call it a day, gives you a nice tight quench and higher compression. Don't have to worry about blowing another headgasket in the future either. :nod::rofl:

Fuel injectors... Sounds like 30# should be plenty. Best place to source them? Rebuilt/flow matched ok to buy such as these ..

If you can find em, grab some Ford 30# SVO sticks, their usually available and cheap.

Edit: TBH though, that cam and stock heads prob won't need more than stock injectors.

Last piece of the puzzle is ordering pushrods. I have the CC pushrod checker tool. I went with LS7 lifters and made one temporarily solid with washers. The heads and deck have been milled/refinished (I'm not 100% sure but i think together around 0.015-0.020") and I went with a 0.039 gasket so I think I should need slightly shorter pushrods. Just want to verify if I did this correctly.

Setting the rocker at zero lash and rotating yielded these results..

How much should you add to account for preload? The rockers are mounted on ARP 7/16" studs.

Hopefully I did this right ?

@ltb1ow @sweetbmxrider @anyonewithvalvetrainexperience!

The last one looks good, are you running NSA or SA?

NSA. So if I did 1/2 turn preload I should add 0.0406" (corrected) to 7.050 rounding to a 7.100" pushrod?

These should be good enough?

Of course pics are blocked at work, but last night it seemed you did not have guideplates on?

No they're on, went with the GMPP, probably should verify they're hardened ..

They adjustable?

The last pattern looks good, what does the patent look like with 7.10" on teh checker?

Non-adj.

7.1" seemed pretty close to stock. Did you mean 7.0"?

You showed 7.05 looking good, then linked a 7.1 PR. So, how does the pattern look when you run it with a 7.1 length?

Maybe you missed my post above, don't you add in lifter preload? If 7.050 worked well on a solid lifter then to achieve that same effective length wouldn't you add 0.04ish (1/2 turn at 0.050"/turn x 1.625 correction since valve is now pivot) so then 7.09 ~ 7.1" pushrod ? Even at 1/4 turn preload you'd want a slightly larger pushrod anyway right?

Yea, sorry missed that aspect.

I just measure and buy as is, never added/subtracted preload etc. That is just me though.
