Hey Guys! It is good to be up and running again. I have two questions for everyone today.
1- I tore down my 396 to find it had closed chamber, rec. port heads, with a casting of 3919840 - When I looked up what these were, in the comments section of the website I used, it said these were COPO heads. I do not want to run rec. port heads on my 496 that I am building, so I was going to trade these for some 781 or 049 casting oval port heads. My question is this, if these are COPO heads, does that mean they are worth more than any old oval port casting head? I really dont need them, but I dont want to get screwed into giving something of value for a dime-a-dozen set of heads.
2- My second question is what is the rod length supposed to be for a 496 stroker? I have seen some advertised with standard length, and other's with a 6.385 length, which is right?

Thanks alot guys, I look forward to your responses!
