Are u interested or just lowballing? RB26 heads stock cost money to buy, then to redo the internals with oversized items cost money parts and labour, then over $1000 for Jun cams, over $1000 for porting polishing and decking and thats on the dirt cheap side. So all in all it all adds up for an item i havent used yet.
If u think another price might be fairer then go ahead and place an offer. As for whats in the internals, i dont know much about the head i asked a machining place to build it for me with Tomei stuff, so i guess ill have to pull it appart and check the parts. I think i might do that, because that price might be on the cheap side.
It cost me a lot more than $4200 to build the head.
