I would be hesitant to get them myself.
I don't see where is says the intake runner size. Flat tappet springs on them.
You usually get what you pay for in heads.
Combustion chamber shape looks dated to me.
Your hyper link didn't take, this should work. http://www.ebay.com/itm/151690545179
You need more info from the seller regards the springs also.
The installed height, the bind height, the open and close #figures.
Otherwise you don't know how they match up to your cam and that is really important.
If I buy heads like this, I buy them bare and add my own parts. I also have a chance to clean up the runners and port match them.
Good luck with your decision......you only get what you pay for especially with all the cheap Chinese crap on the market these days.
