BETA I head will fit on BETA II head NP
I would VIN for correct intake cams though cause it could be 2.0 or 1.8 but i do not think it matters 1.8 is what it is though
but dont put 2.0 cams on a 1.8 engine
everything is the same

oh one beta head differs from the other in that 1 of the heads have 2 thermostat related sensors, and anothers only got 1 figure that out and u will have a lot of information about the type of cylinder you have

Someone said one can swap Beta 2 intake cam into a Beta 1 head. Swap the lifters too, and have one solid and one hydrolic cam? The engines have different lifters, so swaping ONLY the cam will NOT work.
Please advise.

Remember you'll need to swap on your Beta 1 intake manifold. The intake ports on the head are pretty different but nothing a mild port job can't fix! Also is the head your getting already good to go meaning the cams are installed? One pain you get from the switch is you'll have to periodically check the valve lash. Its a VERY tedious job and requires lots of shims of different thicknesses.

Valve length, hydraulic vs Solid
rob40,
You are correct that the valves are different lengths. Cams do swap. 18 months later, my knowledge and experience with Beta engines has tripled. I don't know why anyone would put the loud solid lifters on a Beta 1 engine. The misery and cost of adjusting (coins are $28 ea) is enough alone. The hydraulic lifters are so much better. The Beta 1 makes more horsepower for a reason. - and a machinist told me that .010" - .050" can be removed from the base circle and the hydraulic lifters will fill the gap. I'm going to research more, but that's my plan. Oregon Cam Grinders will regrind a cam for $100+-
et al., I missed third gear in a drag race and hit first. My Beta 1 did at least 10,000 maybe 12.000 RPM for an instant, and still ran for 2 months before it seized. Powdered metal rods are awesome!

The main reason people in Puerto Rico go with Beta II solid lifters is because you can use higher cams with solid lifters.
