is it better to have mla's or hla's ??
i just noticed on webtech that it shows how to install an a new mla head, and it doesnt mention anything about our hla's. just curious ...

 

I don't remember, Tony (random) has talked about them a few times on HA.com before.

 

it depends on what you are using the engine for. For normal driving everyday on the street... HLAs are MUCH better. Quiet and maintance free. They however are not fond of high revs and dirty oil. MLAs are better for high revs. Being a solid lifter instead of a hydralic one, they do not care about how low your oil is or how dirty. They also are not prone to collapsing under high load/rev conditions. However, you will periodically have to get them adjusted and they will start to get noisy before hand.
