All,
I just picked up a Circle-B head, and am going to ship it off to a reputable
and experienced machine shop. I would like some recommendations on shops
with considerable experience in building performance motors. Names and
phone numbers please, because I will need to have a lengthy discussion with
the shop on my needs, and their suggestions.
JK Jackson and Richard Good are certainly high on the list. PAECO in
Alabama also come highly recommended.
Work I would like done is:
- mill the head for 9.6:1 compression
- line-bore the cam bearings to accept needle bearings
- port-matching (I'll be sending the manifolds with the head)
- conversion to roller-rockers
- tubular pushrods
- contour combustion chambers
- glass-peen head
- gas-flow ports and valve pockets
- 3-angle valve seats
- if there is any money left, cc the chambers
The head has been magnafluxed.
I believe that this is the most crucial aspect of building horsepower and
torque (building a survivable motor is the the other crucial ingredient), so
no expense will be spared.
If people have already gone this route, and could share with me their
experiences and advice, I would be delighted to hear from you.
Thanks in advance,
Shane Ingate
