Do yourself a favor and send them to someone who knows what they are doing with them. It may end up being cheaper in the long run and you wont be sorry you did.
I hear ya lol
The 26 cams lift is .490" so you don't need a major port job. A BigBoyz "street" port job is a nice improvement and cost effective; Bean's street port runs about $300. He retains the stock valve sizes and springs, does a multi-angle valve job and works the intake runner/port and lowers the floor on the exhaust port. Machine work to deck heads, drill/tap for compression releases and measuring chamber volume are all extra cost.
A set of his ported heads will work well with your plans and won't break the bank.
Porting, polishing, trimming valve guides ALL a serious balance. Once done cannot be undone with out more down time and rewelding and machining, best to have a pro do and good flow bench test before and after JMO, I have ground alot of valves and reshaped runners it is alot of work but well worth it:s
Feuling 4 valve and American Quantum parts for the 4 valve harley Davidson EVO and Twin Cam Engines.
If I had a ton of money, back in the early days 4 valve heads flowed really good
