what do you think about this head/cam the cam i have is a 232/238 .595/.605 112+4, custom comp cam grind
its also on the xer lobes
original plans was stock head gasket thickness and the afr or etp heads
well money got a lil weird so i had to sell my etp heads and now got the
prc stage 2.5 5.3 heads
so cam:232/238 .595/.605 112+4
heads : prc 5.3 stage 2.5
fast 90 nw 90
fast toys : ram air kit and 85mm lid
pacesetter lth
true duels sweet thunders n dumps
all the bolt ons
tr5 plugs w/ msd wires
what do you think about this combo?
also i have a brand new set of comp 1.75 RR my engine guy said would be fine to use w/ this setup should i or not? he recommend basically that i do so im way swayed towards using them, he said b/c mine now have 100K on them and these are new and fully balanced, but ill see a minimal gain over the stockers

from what my engine guy ( the guy that ground the cam at comp for me )
which also happens to be my tuner he says not in the least.
the duration isnt radical really and its on a 112 + 4
i wanted it on a 110 + 2 but he said the 112 +4 was the better option and would put me in more mid range then down low, i didnt want a cam that was going to be all top end
the cams similar to the g5x2 or texas speed 233/239

I'd sell the Comps and run Harland modified stock rockers.
With a decent head/intake combo like that and all of the bolt-ons, you might see 440~450rwhp out of that cam through the A4. I had it and put down 43x on ported 241's and an LS6 intake through an M6. AFR was 12.7:1 and timing was 27* at WOT. Low rpm driveability is in the tune for the most part. If it bucks/surges on you, it's most likely too much timing and/or too much throttle cracker.

Because it's an OEM design. I don't know of any aftermarket rocker that weighs less than or equal to the stock design....and when you're spinning the motor to 6500+rpms, I wouldn't want to be adding weight to my valvetrain. I think I saw someone mention that the closest ones ones were the YT Ultralites, but even they were a little heavier than stock. Not to mention, the stock rocker arms shouldn't have the potential allignment issues to deal with as they are OEM.

from my understanding the comp cams rockers are balanced and weigh very close to our stock rockers. plus these give me a lil added lift.
i get alot of my parts though comp since its here in memphis i have alot of friends that work there. comp parts are easy for me to get my hands on and usually way cheaper then anywhere else.

i appreciate your opinion very much
thats why i started the thread in the 1st place
i was just stating why i got the rockers in the 1st place, not bashing your opinion or anything. i thank you and evreyone else for there opionions and experience here on these boards.
the cam and heads i was going to be running got changed at the last minute b/c of time and money issues to be honest. started w/ etp or afrs and had to go w/ the texas speed b/c of timeline im on now. i changed the cam to something less aggresive then i origionally intended b/c of tuning and the possiblity of nitrous down the road, thats where the money came in, 1000 more on heads or put that towards a nitous sytem and fuel system upgrade.
i may very well sell these, which will be easy b/c of the discount i got on them and get a better rocker for my combo like the one you mention the harlands. id also considered the yellow terra ultralights like you also mentioned.
