I brazed the ends of the tubes and silver soldered the pipe into the 1/8 NPT fittings .

not in the Ghia , had too many issues ,not the cooling system ! main problem was the 48 tri jets I got that were supposed to be recondition had issues with the dellorto drip in a big way . set me back to much fixing them .now chasing an exhaust leak that may be a cylinder leak . 3 of the 4 CHT's are very close but #2 is 20c lower and it's on the cylinder that I suspect the leak to be from .

looks impressive though and early days but I'd say the cooling system works better than the 911 one on my 2.3 in my Splitty . the same MGL TC-1 gauge and same thermocouples , I've devconed the thermocouple to the spark plug boss(gives me a lower reading, I know) , the same on both engines . the Split has a 103X71 with 8 to 1 comp . the Ghia has 103X78 with 10.5 to comp and has lower CHT's by about 15C . CHT's running around tonight ,30C ambient . 100 C .

What is the melting temperature of the solder you used on the oil squirters?

279 C , if my case ever gets to that temperature I'm in big trouble !

I had a cylinder leak actually on #2 , both #2 and #4 are .003 shorter ,even though the decks are even. we had problems opening up the heads to the big bore because of hard spots in the castings . even though I lapped the heads the worst one ended up on a shorter cylinder, if it had been on the longer cylinder I think the crush in the annealed copper gasket would have sealed it. I've shimmed out the cylinders and will take the heads to another friend with a big Bridgeport to sort out the high spots .

Thanks Benito . Just waiting now for Aaron Roberts to get a bit of time ,he's got a few Auto's to do first that customers are screaming for. I'll have it a Valla next year , the main reason for most of the build of the car is the Raleigh lap dash.

Just a tip given to me by one of Australia's better engine builders. if your building a performance low clearance hi comp engine.After you've done your deck heights and are ready to bolt the heads on , torque up the heads to 25 pounds or so then leave it sit over night for the sealant around the base of the cylinders to go off . then carefully remove the heads and check that the cylinders are even with a straight edge . If not shim out the cylinders that are short . a few thou won't change the comp that much but will cause head leak issues like I had . my #4 and #2 were .003" shorter even though the decks were within .001" of each other .

I guess 40mm exhaust valves are just too big for safety on AMC heads .

Nevermind... Maybe a little welding first?. :evil:
