WOW!!!!! That is just awesome. I bet my iron 427 (4.07" bore) would love those 245cc medium bore heads, and my birthday is in October.........
Honey, I know what I want for my birthday........
That price is for each head
Nevermind.......

Aftermarket castings? Went to your site but couldn't see if they are oem ports or new castings.

1CAMWNDR

iTrader: (21)

Agreed.

1CAMWNDR

They are custom castings.

nice, even with having to buy offset rockers it'll still be $400-500 less than other castings (which also need aftermarket rockers anyways).

Wow. Subscribing!

Is this price for a pair of heads or EACH?

Rise of the Phoenix

iTrader: (27)

Very interesting. Can't wait to find out more about these heads. I'm sure that price is for a set of assembled heads.

Stage7

I'll called. The person on the other line said the price listed was for EACh.

1CAMWNDR

iTrader: (21)

Wha??????? I hope not.
That seems kinda weird. I have never heard of someone buying just one head......

black00ssFL

iTrader: (24)

I take back my previous statement

The Alchemist

iTrader: (19)

They most certainly are for each, or else I got robbed a month or two ago when I spent over $3500 for a set of heads, cam, and rockers.

Rise of the Phoenix

I've seen heads listed like that before, but it's a real dick tease when they do it. Who the "F" buys just one head? List them as a set.

iTrader: (29)

Thats a trap! One head 1200 bucks? Heck no!

Beaflag VonRathburg

Why would anyone think that that is priced per pair? Look at the pricing of similar aftermarket castings. There's not anything out there with this much work into them that prices competitevly.

Engine_HP

iTrader: (1)

IMO they should have left a third NOTE: price listed is for EACH.

Engine_HP

iTrader: (1)

at least other brands lists price perpair.

^ It's just common sense. If you see a 1-7/8ths stepped to 2'' stainless steel header listed as being $300 more than likely you're either thinking this thing is a hunk or **** or priced a piece. Mast doesn't sell hunks of **** so it is obviously the ladder of the two.

So some of us got a little excited and hopeful since it wasn't explained. So we thought they were going to turn the cylinder head market on it's ear. Thanks for telling us how stupid we are and that we need to crawl back under our poor house. .
