Hi

looking to doing a 25/30 build 

I've got the 30 block just looking for a 25 head wanting some tips on how to do it what machining has to be done to make it work??

Use a 25neo head. Far better head.

Depending on the  power  and reliability  you are after will depend on  what work you have to do with it.

I just built  one 25 30 neo reliable  550rwhp on pump  fuel.

Everything  in the  engine is rated for 1200+hp so i know  i will never need to  upgrade anything for more hp.

Cost 20g.

Have you read the RB30 PDF in the RB30 section of Forced Induction?

You can do a cheap job for up to 500hp or you can go all the way like Dave above - depends what you want and how much money you can spend.
