irokin Posted February 7, 2010 Report Posted February 7, 2010 Are you talking about a 3K-B head or a 3K bigport head?
19914afc Posted February 7, 2010 Report Posted February 7, 2010 (edited) Would just like to know how rare are the 3k big port heads? Because I'm buying a ke20 with a 4k but it has a 3k big port head on it. Edited February 7, 2010 by 19914afc
TWF#14 Posted February 7, 2010 Author Report Posted February 7, 2010 Shit got a second thats bout all had some probs and yea 3kb dad always hads crazy ideas he wanted a bigport then a 5k now a 3kb Lol and the bigports heads are pree hard to get a standard one
19914afc Posted February 7, 2010 Report Posted February 7, 2010 Does anyone know hoe much the big-port heads sell for? Sorry to be off topic.
TWF#14 Posted February 7, 2010 Author Report Posted February 7, 2010 I don't relly no when we were look for them the cheapest some one would sell was 150 and that was awesome but 1 guy wanted 800 Lol

TWF#14 Posted February 7, 2010 Author Report Posted February 7, 2010 I sold one recently for $70 but that was to a mate. Depends how stinjy they are
19914afc Posted February 7, 2010 Report Posted February 7, 2010 Ye true, well I'm getting an whole engine (4k with 3k big port head) and a 4speed k40 in the ke20 I'm buying for $600 (the $600 is the price for the car and engine) one little bit of rust and the interior is overrated! but then yes I am buying it from a friend.
silverra23 Posted February 7, 2010 Report Posted February 7, 2010 Bigport heads although considered rare, appear pretty frequently on here and ebay and go for $70-100. I sold one about 12 months ago on ebay for $75 if I recall correctly.
philbey Posted February 8, 2010 Report Posted February 8, 2010 I really don't see why everyones chasing these coveted BP heads anyway, as the writeup in the FAQ says, they're 40 years old, they're probably full of issues and really, 150 bucks will get you a port match job on a much later (and sans welsch plug) 4K head in much better condition. IIRC BP heads are about 29-30mm, my 5K got taken out to 31-32 for 150, matched to my Dellorto manifold.
TWF#14 Posted February 8, 2010 Author Report Posted February 8, 2010 what specs are the 3kb like port sizes and stuff
TWF#14 Posted February 8, 2010 Author Report Posted February 8, 2010 also its for speedway so you carnt port or any of that shit
