i'm looking for an exact head and gasket set up that will work well with my current cam.i've searched and not found the info i'm looking for.after reading posts on dcr i was curious to see where i'm at now but can't find stock short block info or cam timing events for the calculator.i decided to do a set of head but can't afford afr's.i have about $1700 to spend.is it reasonable to expect 4 mph out of the right head setup?i was thinking of tsp's ls6 heads milled for optimal dcr.i've read quite a few posts that say 5.3's are the way to go on a n/a setup,is this true?any help would be greatly appreciated.mods are in the sig.my goal is to have a mid 11 sec car that traps in the mid 11x's.thanks in advance

For that kind of money, I'd look at the TSP CNC ported 243 heads with the competition valve job and the dual spring upgrade. Make sure you get the heads milled to 60-61cc and run a .040-.045 thick head gasket for better quench and more knock resistance. That should easily get you the 4mph you're looking for.

thanks for the help.what would the gains be if i did shell out the cash for the afr205's?i've read that they offer serious midlift flow,but with my verter i spend very little time under 4500.also does anybody think i'd be better off switching cams to a traditional split?i've heard good #'s out of the tsp 228r.thanks again

with a set of tea 1.5s with a 57 cc and the 228 r on a 112 through an m6 i made 436 rw through a hooker catback so the 228 is capable of some good numbers with all the boltons like i have.this h/c package will be for sale shortly,i also have a forged bottom end that will be needing a good home.

Midlift flow does not mean mid-rpm power. It means that the AFR head gives outstanding power in the .300-500" lift range. More airflow in this range has a bigger impact on power than more flow up high because your piston has a stronger draw to incoming air when the valves are in the .300-.400" lift range. Any gains in mid-lift flow show up as more power from idle to redline.

Id also suggest a CNC ported LS6/243 head, with upgraded valves and dual springs. Both patriot and PRC will be able to accomodate you well for a good price. Patriot has a deal going on now for under 1200 bucks. Not sure on the PRC pricing.

Im not convinced yet about the dart heads, even with the PRC CNC port job. I am however anxious to see about the patriot predator castings. Theyre supposedly going to just hit the top of your price range.

I really feel that return on investment drops off around this area, atleast for the bidget minded. With the quality and performance of 1100 dollar heads, its tough to justify spending twice that for an extra 5 to 10 HP.

As for gaskets, I personally like the GM MLS gaskets, though they leave a little to be desired as far as quench and compression. Again, I just cant see spending may times the price of a normal gasket on a set of cometics. A good budget option is the Mr. Gasket .042 composites. The trouble is that theyre composite/graphite, and not MLS. A friend of mine is using them with great results.

Are you planning on replacing that cam or not? What gas do you want to run, 93? What static compression and DCR are you shooting for? Also, how do you feel about flycutting.

And thanks for calling me out, i think this was the first time anyone's done that. Although im still a long way off from Patrick G's level

no problem man.after searching through old threads i saw you always try to help.i'm want to get the best setup possible for the money i have.i would be ok changing the cam if it is going make for a better overall setup.as far as scr and dcr i am hoping that you guys could educate me alittle.it seems from what i've read that around 11.5 is on the high side for a dd,but that with the right dcr is doable on 93.is this correct?also does anybody know where to get the info to calculate my dcr now?thanks again

I like this compression calc. http://www.kb-silvolite.com/calc.php?action=comp

You need the IVC from your cam to calculate DCR though.

is there any way to find the ivc of my cam online and the deck clearance on a stock long block?i think i found everything else for the calculator
