yes another Vinci head test
this one will be on the wife's car. it is to finish up their stage IV package. all information about her 99 formula is here: http://stealthram.com/1999pontiacformula.html
99 pontiac formula
automatic
stock converter
3.23 gears
stock ls1 intake
VHP airlid
VHP air filter
VHP MAF ends
VHP/Crane 1.89 accelerated lift rocker kit
VHP/Crane dual valve springs
bassani 1 5/8" optimum length headers w/hi-flow catted y-pipe
borla catback
on jan 12th, i will be taking it out to the track for some final current numbers on both NA and N2O.
then, on jan 14th, i will put in on the dyno for current numbers as well.
original post about the heads here: https://ls1tech.com/forums/showthrea...highlight=head
was supposed to go on back in november. but, the tranny went out in the 00 formy (my car).
now, what i'm looking for is input on what you are looking for in this test. what parameters? what information about the swap? that way, when this does happen, all your requests about information will be considered. and there won't be any dispute over numbers and how the testing was accomplished.

intake 224cc
exhaust 80cc
chamber 63cc
4.8L heads that VHP CNC ported and added Ferrea 2.02/1.60 valves.
This should make it a little easier for all.

Jay from AS is way behind on orders, and we removed his banner until he makes all the folks whole. Go ahead and post that info, it is a tech board, but keep in mind that he's exactly mr popular in the sponsor feedback forum.

predator-z - thank you.
bigdsz- this test is not to see how it compares to your AS heads. it is to compare against the stock LS1 853 castings that are on her car. there will be no stirring of the pot. thanks for your info though. and as i said, those are not the flow numbers for MY heads. so, hold of on your comments and comparisons until i post them.

majority of port work done out of house to VHP CNC specs they have a CNC profile on disc where they have it done at. all the finesse parts, (bowl area, chamber work, hand porting to get rid of the CNC marks and make final shapes, cutting of the seats and valves, etc) are done in house. only reason why they don't do the CNC part of it is because they don't have a CNC machine.

Can't keep quiet anymore. SAM98WS6 why do you keep following around mrr23 threads and posting up negative comments. I have been following a couple of the threads started by mrr23 and keep seeing you consistantly posting with negative comments. All this thread is about is to state that he is going to provide a back-to-back comparision test.
