I'm assembling a set of 308 QV heads and it seems that my 308QV and 328 manuals both show the specs for the 2 valve springs which are WAY...
Hey Sean... did I speak with you on the phone today? 110 and 250 should still be safe. There is way more danger in a valve bouncing on the seat...
I agree. After all, what is an 84 mondial Euro Cabrio worth these days? It sounds like it could easily cost more to fix than you could ever sell...
hans, why did the heads come off? Valve guides, or?
Man I hate to hear that. I lost my brother the same way. When will people learn????? Driving drunk should have the same consequence as firing a...
ok, well, after I posted that last response I saw the white 308 at the top of this page... it looks pretty dang good. Probably, unless you do...
now that's very interesting. Years ago my dream car was a white Testarossa. I still like them, they're exotic and rare. I've never seen a white...

I'm in Salem, OR about 45 minutes south of Portland. We don't see a lot of Ferraris in Salem. I spotted a 456 parked downtown one night several...
Hey, No Impala bashing!! LOL
It seems like the stock springs coil bind at about .460" lift and I don't remember seat pressure but 90 lbs rings a bell. Sorry, I write this...
I don't want to start a big thing here, and it sounds like you know what you're doing, but I'm a motor guy, and the first thing that entered my...
I've been working on getting titanium retainers for the 308 that will fit the stock spring. I'm also working on putting together an aftermarket...
I don't know man, they look like they will use up a lot of horse power. Wouldn't the cams turn more easily without those things in there??
