Special order, or are those redone?
What did you have done to them, and why is there a difference in calibration shown or at least explain some stuff, (since I've only gone as far as rockers, springs, and taking off the LIM)?

i had them p&p'ed/bigger valves at a local shop, the one is the intake valve(1.8 stock) and the other is the exaust(1.52 stock)130# springs. they should flow a ton more air then before. more air and fuel = more power!!!! yay!

is that foam filler??? is that a bad thing?

Looks like assy lube.

Typically intake valves are larger then exhaust valves. That's why the two are different.

How much did the P&P and larger valves cost?

I remember reading about you helping out on your builds. So where are you getting all the info from to make sure everything is going to mesh well together? Because, I think you just posted about how the build last time wasn't meshed properly.

well last time we ( my uncle and I) rushed to get the engine built once e had teh parts... we dident check clearences ect. this time we are takeing our time measuring everything....atleast twice ..if thast wahat u mean by "mesh"

and yes that is assy lube in that picture,

this engine i am assembeling myself, with supervision from my uncle

and getting the p&p with new guide seals,springs, retainers ect was $450 and the valves were $400 so 850ish all togther

from my acient experience with building engines (yes its been that long ago) you never really knew how well things would work together until you got to the tuning stage. You went for max intake/exhaust flow, made sure clearances were right so as not to destroy anything and built it to be heavy duty. Timing and carb tuning were the variables back then...so much more precise now with the advent of computer controls and tuning.

best of luck 2fast...looking at this stuff brings back some fond memories

T bat you said it right!!! max flow!! thats the key to makeing power
the more you flow the more you get. but one thing on the heads when they are being P&Ped that the person whos porting them must be carefull on is to not port them to big as to decress volocity. so it gets tricky.

2fast4u wat is your 1/4 mile time with all those mods!!!....u beat ur uncles old times with his chevelle or watever it was yet?

not yet,but when its back up and running that 12.11 is mine!!!, when i did the IC install with the p&p sc and n* Tb i hardly picked up any gain because i was running superuntuned ( go ahead and start ripping me) i had a IS3 blower cam and i had a base tune for a xp cam, oops.
and im not sure on the 1/4 mile..im hopeing for atleast a 15.10

good joke man n its a 15.0 flat thanks haha.....wait till the 75 shot goes back in ill get down in the mid 14's dun u worry.....12.11 is awsome wats ur best so far

i wasent aiming that at you lol ,it was just a joke! my best so far was a 13.02.....i did have a 12.99 but on review of the video a leaf blew across the line first

lol... you shouldnt have taped it!

Man, those valves are almost the same size as the ones in my 350 in the Malibu. Drool! Those are some gorgeous heads, I'd love to have those on MY GP. Not that they would do much good, it's just that they look so good.

Tuning the Malibu is like changing the jets, tweaking with the timing, adjusting rear tire pressure, reading the plugs, etc.

Anyway, that's off topic and I'm sorry. Best of luck with your new build.
