We basically went in with the new retainer & gave us a little more pressure so guys can run bigger camshafts, more boost, or more aggressive lobes without risking valve float.

The castings are brand new GM heads that we receive fully assembled & tear down for cnc porting

Jason - What about my special set that I PM'd you about, what are we looking at for a price there?? I may have to jump on this a little early for this price, is that SHIPPED (I hope)?

Thanks dude!

P.S. I will need some other things too, maybe we can work out a package deal?

Will need ARP head bolts/studs, gaskets and new lifters. Do you have the Katech Rod Bolts too?

Interested in the Stage-II heads.

And I'll be the first to ask.... Flow specs for 'em all?

Hey Jason, you need to change the valve size you listed for the 2.5s.. It says 1.55 truck exhaust valve.. Just a heads up before confusion sets in!

Oh yeah, does this mean I get $100 off the heads I just ordered thru Gomer?? That would be nice!!

U guys design a set of these yet that will fit the MS3 without flycutting?

Jason 98 TA

iTrader: (4)

The only way to clear with a MS3 is by using stock valves in a 241 casting. That would be considered a stage 1 style head & ends up pretty cheap if you supply your spring kit

iTrader: (2)

What do you think my gains would be over stock heads with this stage one 241 head? How would they compare to a stage 2.5 with flycut pistons as far as HP? Can you PM me a quote for those heads? So they are the stage one CNC'd new GM heads?


Ive been looking for a way to upgrade my current set-up of stock heads (PRC gold springs with less than 600 miles on them) with the MS3 so if you could PM me I would greatly appreciate it.


Thanks,

The pricing is before shipping!

For a limited time we are also offering these heads hand finished at no additional charge! The hand finishing helps a few cfm & really makes the cylinder heads look awesome!! I'll get new flow #'s for you guys in the morning.

which would be a good setup for a nitrous application. only doing 150 dry have NO intensions of going higher

Jason I'm in the same boat as 99whitews6 and would like some info on ball park power and price (reusing my PRCs) with the stage 1 style. My car is a monster with the MS3 and a 150 shot but I'm getting bored fast even though I've only had the cam a couple of weeks. Do you think it would really be worth using stock valves since I spray. Would you ever reccomend fly cutting on a nitrous car with stock pistons, or is that asking for to much trouble?

Thanks,
Andrew
