    Well.... I have to buy new heads since I cant get a decent set of cores. So i have decied to look tward the cast darts. Does anyone know if these headsflow better than stock? Do I need to run different lenght pushros and valves?

    Of course they are better than stock but it costs also, I have a nice set of 990's if you want to go on a budget!..

    I've got the Merlins on mine now (as you know) and I was spinning 6K on Saguaro on Sunday. Runs like a champ. Now just have to fine tune it a little.

    I read a post that says you should lock out the timing at 50. I read it on ***boat, so it must be true.....

    How much better do they flow over the 990's? What would be better 320cc's or 345cc's with the merlins? the reason i ask is because the merlins bare are only $489ea through jegs.
    Here is my recipe.
    454 .30 over
    10.7-1 comp (if I run a 119 cc head)
    rectangle port tunnel ram with 2 holley 750's dp flowed by braswell
    full msd ignition(dist,wires,6al and coil)
    cam is a clay smith 256@.50 .615 lift 108lobe
    This will be running in a 18ft jet with a "B" impeller. I am trying to spin 5800r's

    You should be spinning better than 5800 with a b as I'm doing it with an A cut.
