Laecaon Posted April 4, 2012 Report Share Posted April 4, 2012 Looking for an Open head. Square exhaust ports. Link to comment
crackerjack69 Posted April 4, 2012 Report Share Posted April 4, 2012 I've got a semi-closed A87, would that work? Link to comment
Laecaon Posted April 4, 2012 Author Report Share Posted April 4, 2012 Not aware of a semi closed. Would need to figure out the CC first... My future engine setup is just about pushing what is safe CR. Link to comment
crackerjack69 Posted April 4, 2012 Report Share Posted April 4, 2012 bet Mike would know... Link to comment
hobbes_the_cat Posted April 4, 2012 Report Share Posted April 4, 2012 What is a semi closed A87? Never heard of that. You sure it's not a closed chamber? Link to comment
datzenmike Posted April 4, 2012 Report Share Posted April 4, 2012 Why not the more common U-67. They only came in open chamber 45.3cc volume. You would have to drill two small water holes for the coolant passages in your intake. Big valves and ports and square exhaust. Link to comment

I dont think I have ever laid eyes on a U67 or seen one being sold. I always thought A87's were most common next to 210s. So sure U67 too! Link to comment
crackerjack69 Posted April 4, 2012 Report Share Posted April 4, 2012 I've seen a lot of U67's at the PnP lately. I always check the heads on the 620's when I go. see mostly u67, and a87. and few w53 or 58 smog heads. Link to comment

Im just scared about most of them currently at the JY, as the most recent vehicles were placed on the lots like 2 weeks ago, and we have had lots of rain. Link to comment
DAT510 Posted April 15, 2012 Report Share Posted April 15, 2012 Free bump... Is this Semi closed or closed??? Link to comment
crackerjack69 Posted April 15, 2012 Report Share Posted April 15, 2012 That's a closed chamber head. Link to comment
hobbes_the_cat Posted April 15, 2012 Report Share Posted April 15, 2012 I still have never heard of or seen a "semi closed" chamber L series head. Is that just a different way to say open chamber? Link to comment
DAT510 Posted April 15, 2012 Report Share Posted April 15, 2012 That's a closed chamber head. Oics of semi closed head!! :lol: Link to comment
Dirttrack510 Posted April 15, 2012 Report Share Posted April 15, 2012 I have a open W58 round port head I'd sell or trade for any closed chamber head. Link to comment
Laecaon Posted April 15, 2012 Author Report Share Posted April 15, 2012 Square exhaust ports. But thanks. I have to have a Open head. At 45.3 CC (volume of an open head) I will be at 9.3:1 CR. Link to comment
Dirttrack510 Posted April 15, 2012 Report Share Posted April 15, 2012 just so you know, you can use a round port head with a square port exhaust, but not a square port head with a round port exhaust. Link to comment
Laecaon Posted April 15, 2012 Author Report Share Posted April 15, 2012 I am aware. I just dont want a round port. Link to comment
wayno Posted April 16, 2012 Report Share Posted April 16, 2012 Have you found the head you need? Do you have a closed chamber to trade me? Link to comment
Laecaon Posted April 16, 2012 Author Report Share Posted April 16, 2012 Still looking. Only head I have is a 210 head. Link to comment
Laecaon Posted April 20, 2012 Author Report Share Posted April 20, 2012 Got my block back. Reassembling now. I need a head! (no misquoting now). Anyone? Link to comment
hobbes_the_cat Posted April 20, 2012 Report Share Posted April 20, 2012 How complete does it need to be? I am pulling apart a L20 with an A87 but it was run out of oil. Still runs fine (besides the rods knocking) and SUPER clean on the inside, no noise from the top end. I'm pulling it apart this weekend and will let you know if it is an open chamber. Link to comment
EricJB Posted April 20, 2012 Report Share Posted April 20, 2012 I have an open a87 with Z valve seats installed. It is clean, but absolutely bare. Do you have a core head to pull hardware from? I would have to dig around for the hardware ( and the head for that matter) I would need to get $100.00 for it (bare) to pay for the seat install. Link to comment
