Re: ported LS1/LS6/6.0L heads between GTP and race-prep, who is better? Race-Prep does ALL my cylinder heads and LS1 block work. Their workmanship and customer service is second to NONE. I would put their heads against anyones in the industry. I have several h/c cars that perform well beyond expectation! I.E. Micahjam's car: 6.0 S2 heads AAP 230 cam and AAP tuning pulled 447rwhp and 418 rwtq through MAC headers w/single cutout and 17x11 SS wheels and 315 nittos! With an underdrive pulley the l/t's that we recently put on and some more tuning we could probably could get upwards of 460~rwhp. I have used and purchased GTP products before and can appreciate their quality. But for being local to us here in So.Cal. there is no other head porter that I'd ever trust!!

Re: ported LS1/LS6/6.0L heads between GTP and race-prep, who is better? I agree on the remarks regarding Race Prep's quality however I know for a fact Andy's Auto does not currently use Race Prep. I am not trying to start a flame war and I realize this is my first post but I assure you it is accurate iformation. I was told by Andy's Auto my heads were sent to Race Prep earlier this year for head work. I was notified by Andy's Auto they came back with an issue and had to be sent to another shop to correct the problem. Due to other issues with Andy's I called Race Prep to inquire about the problem with the machine work on my heads. They informed me they had NOT received my heads or any work from Andy's this year. So, it seems I was told a reputable shop (Race Prep) was doing the machining when in fact their name was only used as a ploy. I know others who have work done at Race Prep and it is second to none however Andy's Automotive has been less then truthfull with me and does NOT use Race Prep as of this year.
I think others should know hte truth.

I'm not sure who that is but I hope that you and Mark from AAP get stuff resolved.

He has full right to bash! I fully know his situation with Andy's Auto, and he received a royal screwing of the highest possible order. Believe you me, he has been KIND in his recent posts regarding AAP, compared to the potential verbal barrage he could have rightfully spewed forth. He has not been the only one to have been taken for a ride. There will be more victims to come forward, as soon as legal matters allow such an action.
As for you, I'd suggest getting a broader view of things, before you pass quick judgement on an issue you know nothing about.

First off Blown whatever...
The post made by Abdullah specifically states the differences between heads and who is better. I dont see anywhere in the subject line where it says, "bash on sponsors" while screwing with a fellow board members post.
If he wants to bash then fine, but do it somewhere else...
Let me guess, you just registered today, and probably have less than 2 posts... <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />

Re: ported LS1/LS6/6.0L heads between GTP and race-prep, who is better? 95383 and Blown382cid,
both of you guys/gals need to chill out.
I second what SSBoy has to say.
Why do you and 95383 need to create a new identity to talk smack and flame Andy's? I am sure that both of you probably have been a member on this board and LS1.com for awhile under a different names, so what gives? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
If both of you have something to say, be a man and say it with people knowing who you are and not some assumed identity!!!
If you don't like the shop, that's cool, I can understand where you are coming from because I have had a few run ins with bad shops in my area also, but this kind've crap needs to be dealt with off line, especially when the vendor is a sponsor.

Re: ported LS1/LS6/6.0L heads between GTP and race-prep, who is better? Abdullah, no those were not race prep heads. They were another head porter that AAP used before Race Prep, that time wasn't that great, the had no tuning and was raced at a shitty track in the summer heat, it then went in for the new motor. I just got back my AAP 388 and yes those 6.0 heads are done by Race Prep, they flow 352 cfm @.600 intake and 242cfm @.600 exhaust.

Re: ported LS1/LS6/6.0L heads between GTP and race-prep, who is better? Linear Velocity, how much race-prep charged for porting the 6.0L heads alone? how about the custom matched cam?
do you have any dyno/track numbers for your 388 motor?

Re: ported LS1/LS6/6.0L heads between GTP and race-prep, who is better? My AAP (Raceprep) heads flowed 342/237 @ .600" and made awesome power on my stock bottom end. Now we'll see how they on the 400ci block.

Re: ported LS1/LS6/6.0L heads between GTP and race-prep, who is better? Micah did you blow your motor up already? Just buy my motor and put down some real power. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: ported LS1/LS6/6.0L heads between GTP and race-prep, who is better? Chime in here if your gutted drag car weighs next to nothing and has such a big converter it can barely move except at WOT ! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
Sorry Terry, couldn't resist. I bet Micah's motor would come very close in a stripped 3100 lb. chassis. Oh, and thanks for not blasting me in my previous posts, I know I'm slow - and heavy. If I'm gonna get serious about racing I'd need a bigger converter and start dropping weight. Probably not gonna happen since mine's a daily driver and I enjoy the creature comforts. you know, like A/C, power steering, carpet. <img border="0" title="" alt="[Razz]" src="gr_images/icons/tongue.gif" />
