Jim,

Hope all is going well up north. I am curious as to where one finds out what replacement parts NHRA has approved. I was originally told that the OEM must contact NHRA and certify that they are listing the part as a replacement part. The only way to find out was contact NHRA.Then I was told replacement parts are placed on the Engine Build sheet.

If the E head is approved as a replacement for the RA IV combo in stock for 2008 this will change the direction I might go with the two engines I am building.I have seen some try the head with little sucess or I should say below expected returns on stocker type engines. But racing Pontiacs for all these years they worked well on a all out bracket engine for me and I have my own ideas how they might work on a low lift type set up on a stocker and would love to try based on acceptance and HP rating.

Thanks
Don
