I can buy a new ITR bare head for 600 and build a new valvetrain (using non ITR parts). Or I can get my current b18c1 head PNP and build a new valvetrain on it also, and suffer downtime. I know a custom PNP would be better than the ITR PNP, but how much better? Would it be worth the downtime and extra $$$ ?

 

yes it is worth the downtime... you will love the high end flow of the fully P&P head

 

my friend bought a bare ITR head from Honda and it wasn't ported. i was told the port is in house issue and only comes equipped this way on complete b1c5's or ITR cars. trust me. i've seen the head and it's not ported or polished in any way.

 

Thanks, that saved me 600 dollars.
I live in Texas, so I was thinking of getting a PNP from Endyn. They have three options, ranging from 800 to 1500. I am thinking of getting either the 800 or 1100. Tell me what you guys think. Here is the difference:

Basic Head Package: $795.00

Square head by milling the deck parallel to the camshaft bores.
Mill chamber reliefs around each valve seat.
Custom radius/discrete valve job. Larger than stock seats at no additional charge. Seat heights set to within .001" intake and exhaust to insure the same piston to valve clearance in each cylinder.
Rework port bowls and blend into seat asymmetric seat radii.
Blend and smooth chamber.
Match intake entries and exhaust port exits to spec.
Mill head to CC specification.
CNC chamber rework to match larger bore diameters adds $100.00
Assemble with new Honda valve seals and valves / springs / retainers requested.

Full-Ported Head Package: $1095.00

Includes all of the above.
Full chamber rework.
Full intake port rework.
Full exhaust port rework.
Spot flow ports to verify results.
CNC chamber rework to match larger bore diameters adds $100.00.
Conversion of VTEC heads to fit non-VTEC blocks at no additional charge.

I was wondering if I should buy the new valvetrain before I get the PNP so that they know what I am running and can customize it? Make sense?

 

I would just let endyn know what brand of valvetrain you were considering and see if they say if that would be in your best interests for the head they are going to do for you, alot easier then buying twice.
I also think for the extra 300 I would go for the full pnp, again you won't have to upgrade it later and pay more than if you just did it from the start.
