Wanted to to know what i can expect to gain from switching heads, i bought these heads last year but they have been sitting:

finally got around to boring a 6.0l block 30 over and got a forged set up it in, compression is going to be the same maybe a little more than stock.

Just wanted to know what I can expect to see from switching heads + cam, et or hp gain.

Car has a DP nitrous set up with a 32 get to start with.

car went 9.89 at 133 on a 200* plate

 

So the 243 castings you have now are not ported? If that's the case, I think you could realistically pick up 40+ HP.

 

NA on a 370 it'll pick up probably 20-30HP vs ported 243s depending on the cam. On the spray, you might touch 9.6x.

The thicker casting makes it better for even more spray. If you get to a 300 shot or more, it'd be worth the swap.

 

appreciate the input, i got a new converter which was my issue before going in the 9s at only 133 but having a 1.27 60' so im hoping for low 9s with the new top end. I plan to spray a 36 or 38 jet

 

LSxSprayed,


Our exhaust port setup on that head is nasty. With you spraying 200+, expect to see some wicked gains.
