red13 Posted August 1, 2014 Report Share Posted August 1, 2014 Im looking around at different option. Getting a head for my l16 is been little tricky and difficult. I just bought a w53 closed head didnt realize till I got it, but the mating surface has extra pits. Anyways Im still hunting, but while I wait maybe I can get some crazy thought going. I seethe forums and how people talk about putting a l20b head on a z24 block. Well my question is can you put a z24 head on a l16 block. one reason I ask is besides doing it ratsun style It seems easier to get ahold of one of these heads then a closed head.

wayno Posted August 1, 2014 Report Share Posted August 1, 2014 I seriously doubt it will have good compression numbers, likely 6 to 1 or something even lower, I am guessing the ridiculous, but it would not surprise me at all. The L16 likes L16 heads, it's one of the few blocks that it's not good to change the head unless you are going to use different pistons. BTW, the L16 likes to rev, the Z24 head is made for torque.

datzenmike Posted August 1, 2014 Report Share Posted August 1, 2014 Z24 or Z22 head from a 720 on an L16 gives 6.6 compression. The smaller chamber Z20 head from a Mileage option 720 would give 7.7. I just bought a w53 closed head didnt realize till I got it, but the mating surface has extra pits. As the closed chamber head also lowers the compression slightly (8.21) on an L16 why not have the surface plained slightly? It will remove the pits and raise the compression. Quote Link to comment
red13 Posted August 1, 2014 Author Report Share Posted August 1, 2014 the holes are about 1/8"-1/4" deep. Quote Link to comment
laotsu Posted August 1, 2014 Report Share Posted August 1, 2014 I have am L16 with a W53 on it right now. It runs fine, a little sluggish getting up to speed but it runs. Quote Link to comment
datzenmike Posted August 1, 2014 Report Share Posted August 1, 2014 the holes are about 1/8"-1/4" deep. MIG or TIG weld (if you have one) and then have it milled. Quote Link to comment
red13 Posted August 1, 2014 Author Report Share Posted August 1, 2014 MIG or TIG weld (if you have one) and then have it milled. For what it will cost and do a valve job and everything I've found some heads that are actually rebuilt. Quote Link to comment
red13 Posted August 1, 2014 Author Report Share Posted August 1, 2014 I have am L16 with a W53 on it right now. It runs fine, a little sluggish getting up to speed but it runs. what i want to do is run an a87 closed head with 240z l24 flat top pistons with valve reliefs Quote Link to comment
laotsu Posted August 1, 2014 Report Share Posted August 1, 2014 I have a running '77 kingcab that I can't get to smog. You could buy it and swap in the L20b and have a super straight parts truck... Quote Link to comment
red13 Posted August 1, 2014 Author Report Share Posted August 1, 2014 I'm trying to keep it original with the l16 the only upgrade was the 5 speed,but what u selling the tuck for? Quote Link to comment
datzenmike Posted August 2, 2014 Report Share Posted August 2, 2014 what i want to do is run an a87 closed head with 240z l24 flat top pistons with valve reliefs L16 bored out to 86mm from 83mm? and flattop L28 pistons is 10.3 compression with a stock head. If using an A-87 peanut head it's 9.822, much better I'm trying to keep it original with the l16 the only upgrade was the 5 speed,but what u selling the tuck for? Hardly original with a 5 speed, A87 head and L28 flattops now is it? You won't be able to tell the difference if you put an L20B in there. Only difference is it's 3/4" taller and makes about 20 more hp, which is way more than flattops and A-87 head.. Quote Link to comment
red13 Posted August 2, 2014 Author Report Share Posted August 2, 2014 im already deep in the l16 anyways. wasted to much money on non sense and people. I did come across this for anyone that needs more info. http://newprotest.org/projects/510/jasonGray.pl Quote Link to comment
