How Are These Heads ???
 

I found these on Ebay. They look like no name brand. Are they any good.

I blew a head gasket and ruined a head . They were stock Merc. magnum heads with inconel valves. The valves have less than 50 Hrs on them. I want to buy a bear head and re use the valves.

I dont know enough about heads to know what to look for. They are going on a 468 ci, with 8.9 : 1 pistons. and a 177 blower with a intercoller .

Any help is appreciated

Thanks

Pro Topline makes excellent heads. Very good price for them.
You have to make sure the valves and guides are the same size as yours.

"no name" brand would make me a little nervous. If it were me I'd call the seller and ask who the manufacturer is. And get some details, so these guys here can offer advice. Good luck!!

Pro Thunder is made by Pro Topline.

Those look like a Pro Comp head.

I have a fresh set of 188 {large Rect port} GM heads with Inconel valves / Isky springs
and mild port clean-up I can sell for less than the cost of those bare....
Fresh..never run

If they are Pro-Comp (many times advertised to sound like Pro-Toplines) stay away. Chinese copycat's that are sold thru E-Bay. Liberty and others starting to sell as 'house brands.'

Most will say they are made in Australia, but that's a lie. Why would you buy something that is being lied about by the manufacturer or distributor ?

Do any red flags pop up from the price ?

Reason why this **** is on E-Bay and not at your Pro-Shop. Okay,Pro Shop that cares. :D
