Absolute Speed heads on the way!!!!!!!!!!
ive been researching heads for months now before coming to a decision. I talked to Jay today for a good while about my specific application and the heads are in the making
I decided to go with a stage II 5.7 head with 2.02/1.57 rev stainless valves and comp 978 springs and titanium retainers. I wanted to stay close to stock compression because I may wanna go with some forced air or juice down the road.....besides i think these heads are gonna flow good enough for me with the stock compression
Anyway, im pretty stoked about it....so I thought id share my excitement with my boys here Please feel free to give me your opinions/advice/input about my decision and maybe past experience with Jay or with my application. Later yall Last edited by The35thZ; Aug 12, 2004 at 11:59 PM.

And also the tune and supportive boltons have a lot to do with it.
The heads I ordered are going to be 10:9.1 because I would rather have room for a larger cam than a ton of compression.
I have a friend that dynoed 438 with a 224 cam plus all bolt ons in a m6 car with 10 bolt with 410`s and jays 5.3 stage 2 heads

When my stuff comes in and I get it all tuned up, then I guess we will know what kind of power my setup makes. I just look at the guys that post up these awesome numbers and sometimes if you look into it enough, you can find out why they are making more power than others with similar setups.
It’s all about details…
Jamie, I look forward to tuning your car this weekend or next. I'll call you later.

Cars that make over 400 hp with stock heads and a 224 cams are not the norm! Ofcourse there are some phreaks out there. Most are 2002`s
Most are in the 370-390 range depending on which boltons the car has. Ofcourse the open headers dont hurt his combo at all.Most of the guys on this board that the really have stock heads and make over 400 rwhp have larger cams. Not everyone who claims stock heads have stock unmilled untouched heads. I have seen a guy from this board who claims to have stock heads and posts great dyno numbers but I have seen the car and It has ls6 heads on it. Maby they are stock lol . Just not stock on a 98 f-body. Ya just never know ..I think your goal is very realistic which is a good thing. Some guys just want 450 from buying a lid and catback.
