Piers, Thanks For The Great Head

I had been putting this off for awhile only because I really dont like writing but I saw another thread about porting that got me thinking and I think it's the very least I can do.

I now have about 1000 miles on my PDR stage 2 O-ringed head with a .010 gasket and studs and I am very happy with the results here is what I have seen.

Before head 3 runs on dyno all runs pegged 1600* pyro max rwhp 398.9 (boy was I ******)
After head
first run on dyno around 1350* (I say around because I was so suprised to see it so low I didn't get a close enough look)
second run pyro right at 1400*
third run pyro right at 1450*
That made me happy to say the least, but a added bonus for me was finally breaking 400 rwhp. 431 to be exact.
I figure a good 200* drop in EGT's and 30 rwhp.
Thanks again Piers and hope to see ya again soon.
Jeff
