[cals400ex]

i say buy a service manual and do the installation work yourself. it isn't that difficult and you will learn a lot throughout the adventure.........

CT racing. They are the ****!

I agree with Cals400ex, I did a piston and cam rebuild myself. I had a machine shop do the port and polish along with a valve job. Just make sure you have a service manual right beside you. It is probably a fraction of the cost!

You can always ask any questions you have to the helpful guys on here.

Sparks or TC you would be waiting a while. Just have Baldwin or GT Thunder port/polish your head with the valve job, heavy duty head studs and what not, then do the rest yourself, or have somebody local do it...
