That's what I'm talking about. From the factory, the heads are already pretty well optimized. There's not a lot of room for improvement with just a port and polish job.
When the guy looked at my heads he nearly had a hard attack He compared my heads to LS heads and he said these are the biggest ports his ever seen on a stock car he said he could port them but i had to wait 3 3months i grabbed my heads and went on my merry way back to the shop to give them a clean and put them back on i will eventually do my heads and i will report back on gains and dyno charts but not anytime in the next 3 months i would like to see the dyno sheets to confirm 40hp its not that i dont believe it but confirmation would be great I sourced some heads from Dime racing for a customer i will post up some pics soon |

Yes, I believe my dyno run with ecu tune, and longtube headers showed around 430-440 whp (can't remember now).
My gains at EC in Houston on my 507 from just the V5 tune were 17 whp (427.6 to 444.85) with a 13 gain in torque. Added ROW boxes after but haven't found the time to see the additional gain, I'm guessing maybe 10 whp, so think I'm around 455 whp now. |
My C63 sedan is decade 1 - October build. I was thinking end of Nov delivery. Reading this thread gives me hope of a early to mid Nov pick up.

My english was the issue apparently? That's funny. Should have read more carefully.
Yes, it showed about a 40whp jump after the p&p. Even I had my head scratching to see if it made sense. But it is what it is. I'll find out better what the actual number is hopefully in few weeks on their new dyno. |

Did the ported heads make a difference in power?
