Johnny can remove and replace the head, cylinder or anything else you want, but does NOT do the actual machine work.
He can ship the head to Carpenter and have it back, ready to instal in 2-3 weeks.
The regular CnC ported head isn't listed on Carpenter's web site. You have to call for it.
I can't tell you about a power increase, because I added a 1397, and Carpenter cams at the same time.
It made like 195 hp, but that was through a stock exhaust. I would expect another 15hp with a BDE GenIII, or a HMF Big Bird, maybe more.
I've had 2 stock valve heads and 1 big valve head done there and they turnaround time and the work was flawless!
I'll post some pictures, but I gotta go to work now. It'll be a couple of days.
