Heat Exchangers for 914-6 Options

[Mike Knox]

As many of you are aware, for several years I've been converting my 1974 to a 3.2 914/6. For nearly two years it's been on jackstands. Well I'm getting close to completion, and I need to source up to date heat exchangers.

I have a set of used OEM exchangers, but the flange thickness is different, (IMG:style_emoticons/default/headbang.gif) (thinner) and they won't work without spacers, or reseating all the head studs. So I need to find someone who can supply me a set that will work with a 3.2.

Any guidance will be appreciated.

Mike,

I think you have answered your own questions. Either swap out the studs or use spacers. Given the likelihood of problems removing the old studs I would be inclined to think spacers would be the best path. I would be interested in opinions of why this wouldn't be a viable solution.

Hi John,

I tried the spacer route. It's hard to find the right size at a decent price. I finally located some stainless steel spacers at Fastenal. Had to order them twice, and they cost $1.25 each. After the install, the exchangers were still wobbily. I have yet to turn this beast over, but I'm sure that I'm going to have some exhaust leakage.

I know that spacer cost vs new exchanger cost makes $1.25 per spacer seem pretty cheap. I just want to make sure it's the best solution. Heck I don't even know if using OEM exchangers with a 3.2 is a good thing to do. After all, there's a lot of difference between a 2.0 liter six and a 3.2 liter six.

I appreciate your input THANKS!!
