Highly considering getting mine done while i build my block but just not sure if its in my budget. Who had a pnp 25 head and what did you pay?

Ive considered doing it myself but unsure of myself as i never done one before.

Anyone have any pictures of their rb25 port and polished head? Anything special or anything need special attention on a 25?

Get the head flow benched before and after to see if you gained anything if you do port it.

removing the exhaust humps, cleaning up the ridges in the valve bowls and port matching manifolds can easily be done at home.. just do it before you have a valve grind done... Just in case you scuff a valve seat or something.
