 Re: head work
You do not have to do change your pistons for head work.

 Re: head work
Don"t deck the heads ,have Wayne at harahan auto and machine shop, harahan la. put in the manley stainless valves, these are performance valves that are undercut for flow,and high temp alloy, 30 thou over size , he can also clean up the flow. You will get a true 3 angle valve job. it cost less than evt or the boat dr and you will be real happy with the work. JD

 Re: head work
All depends on how well the stock valves seated.

 Re: head work
Head work defined in simple terms. you can shave (deck) heads to boost compression you can port and polish the air flow passages to the combustion chamber you can put oversize valves for more flow you can reseat/ recut the valve heads and seats to ensure you have as little leakdown as possible
The basic function of a cylinder head is to seal the top of the cylinder bore, allow the intake charge to enter the cylinder, hold high compression forces, withstand the explosion of the power stroke, and allow the exhaust gas to escape. The more efficent you can make the cylinder head work, the more gains you see.
