Which would be more beneficial, getting the head extrude honed with a 5angle valve job or have it ported and polished with the 5angle valve job? Anyone know a good shop to get the head ported and polished in the US (prefferably Florida). Should i replace my valves or just get them polished and the valve face ceramic coated? Are the valve guides easily replaceable?

damn that was alot of questions....sorry about that

Talk to Andreas. He also lives in Florida . Here is a his answer to a question I had about doing some headwork.

Ported heads for $850 shipped with a core and $1,050 without a core. This includes polished combustion chambers, valve job, ported and polished exhaust ports, ported intake ports left rough for better fuel atomisation, match port both intake and exhaust to factory gaskets. Heads will take about 3-4 weeks to be done since I only get to do this on the weekends. If you want valve springs and retainers add about $600 to the cost above.

oooo thanks man! I searched for port and polish but got nothing hmmm well at least youll find something now if you search for it

what about the intake runners on the ITB manifold....is it worth while to try and open these up? Or fabricate a new top half with larger runners?

well the ports are pretty huge stock comparing a regular sr20 to the pulsar sr20
