Can he post prices or is that confidential too??

since I am not a forum sponsor I don't think I can post prices..maybe a moderator can ok it.. you can PM me..MRC motorsports will also be dealer.

 

very nice, I'm no cylinder head guy.. but that porsche head looks completely different! I'll be keeping an eye out for what MRC has in store with dealing your products and what we hear back from gains.

Any insight to what kind heads you gonna offer? Like stage 1, 2, 3 or something?

 

yep...

or can you pm me a price to fix mine? i incinergrated a piston or two

 

We went with a level 2 I gues you can call it..We did upgrade the entire valve train but kept stock size,I guess a level 3 would be an oversized valve job and a really aggressive port job..

 

I gotta say Dave...very nice job on the Porsche head

 

guess what....flow numbers don't always tell you a damn thing either, because, like anything else, it is highly subjective. It can flow more cfm...but guess what? If it does so with reduced velocity, it can be a giant waste of time.

The bench #'s might be good to make people oooh and ahhhh, but I am sure what Dave wants to know from his customers is "how much more power did it lay down" on a before/after basis

 

FYI guys, dave has done some heads for some serious players in the industry going back quite a few years..I picked up my heads yesterday and let me tell yoo, a work of friggin art!I am almost sad to put them on the car their so pretty.. Dave also took some time to do a little secret weapon for me no one else has done yet that I feel will give me a little edge on some people at the staging line.. I took a few pics of the heads and will post them tommorow, I want to take a few more in better lighting conditions.But I tell you one thing, big props to Dave at headgames, he will be doing all our head work from this day on.Anyone with any inquries feel free to contact me as we are official HeadGames distributors..

That seriously is one of the most intelligent posts I have read in a long time..it's so true. I have seen heads on the bench that make me feel like a super hero but once they get on the car it runs like a dog with flees...most can't believe the flowbench can lie to us in some respects, it is an awsome tool, but can not be always trusted. At least that is my opinion, and I base that on me setting world records with some heads that have never seen the flowbench. Experience, and rational thought plays a bigger role then any tool I have used.

 

double post...sorry

 

And thank you all for the kind words..

I am proud to say that my heads run as good as they look as well..

 

looking forward to the outcome Dave

I hear a lot about you from Honda people that actually run their cars at the track with impressive times.

 

We have made 1,080whp from a 1.8GSR Honda and 976whp from a 1.6 Honda..1,098whp with the 2.0 Mitsu...1,800+ from the 2JZ..alot of HIGH hp race stuff..the stuff you see in these applications and the failures really help when building a indesructable street head, when it comes to who's components and materials can handle anything you dish out..with 45-75lbs of boost you will see some things fail or survive.

 

Here are some pics I promised.I will not show my secret weapon,however, you can not tell me these heads are not a work of art...
I will be selling a fully built Race head for around $3990-$4500 including the valve train.Perhaps Dave will chime in and go over what will be included with the heads ordered through MRC motorsports.

 

looks good - mine are better j/k

 

thats looks pretty sweet. Can you give an exact brake down of what all is included for the $3990-$4500 Thanks!

 

Looking good!! Mine are a weee bit different (not done through HeadGames, but rather my own engine builder/guru/swame) in their porting, but very similar overall (my car is staying NA). I am jealous of the shiny new valves you guys got...being NA, mine stayed stock

Adam

 

The verdict is in..Dave is my new bestest friend....
