Got my head back today. Everything looks good. Milled .070" off the head (which had never been milled), smoothed out the exhaust ports and ground down the lip underneath the valve faces, 30* intake valves, 3-angle exhausts with 45* valves, Isky double valve springs with steel retainers, Isky pushrods and lifters. It's all buttoned up on the block with the valves adjusted to .016". Tomorrow I'll fill it with oil and coolant and crank it up. Fingers crossed that whatever my problem was before is gone now.

Did you check for coil bind this time ? Also... I take it that after removing the .070" of the head's surface, you did check the pushrods for length/operation? And valve guide length/interference issues? They *could possibly be* too long now (removed.070" from head)

Shaving the head can *possibly* make the pushrods act as if they were "longer", further complicating coil bind, and or valve guide length issues.

You may very well be OK, but... *you won't know for sure* (until it's too late) unless you check. Because just crossing your fingers doesn't check nor readjust clearances/lengths ya know.........

Also, on most engines.... the intake valve clearance is less than the exhaust valve clearance. Usually the exhaust valves are set .02 to to .03. looser than the intakes. Of course this varies from engine to engine (brand/size/designation/family etc)

This due to exhaust valve needs more clearance due to it's greater heat expansion.

The book says .016-.018 for all. JUST FOR NOW... I highly suggest to set the all valve clearances , especially the exhaust valves , a bit *on the loose side* until things break in/wear in.

Why? Because when valves have been ground, and new lifters/camshaft have been installed, you need to allow for break in of new valve train parts. You do not want the exhaust valves to 'run too tight" because you'll might burn the valve/s

This will keep you from *possibly* burning one of more exhaust valves while they bed/break in. Might want to re-adjust the valves to allow for this.......

I'd set the exhaust valves a thousandths or two looser than the intakes. At least until you get some miles on the engine and break in the valve train. You stated you set all valves to .016".

Also don't expect the machine shop to check for pushrod length/valve guide length issues. Unless of course they have the rest of the engine (and the cam installed in it) there too. You need to do this before cranking/running the engine too

Just trying to help.........

Yeah I've been DD'ing it since I got it back together. I'm at around 500 miles on the new engine. My only complaint is that I originally used a 190* thermostat which left my temp needle about 3/4 of the way up. I switched to a 159* thermostat and now it runs a little too cool. It performed better when it ran warmer but I'm afraid to let it run that warm once it starts hitting 100* here this summer. I'll probably try to swap it out soon for something between the two temps.

Good to hear. Can you get a 180 or 185* for it?

I need to look. I'm sure I had something like that in the old motor.

Actually yes, I just looked at Swedish Treasures and they have a 180* (81C) thermostat. What I have now is 158*(70C).

Pretty sure my old man ran a 180 or 185 in all of the pushrod motors he built. That was in southwest VA so similar climate

Maybe the 190* just needed to break in but there were times it would peg the gauge and I'm not cool with that. I'll try a 180* and see how it goes. It's too cool to be performing at it's best as-is. I do know that.

B18/B20s can be notorious for air trapped in the head after having drained the coolant system and refilled.

. Fill coolant system with the engine block drain cracked open to let some of the air escape.

Also use a T stat with the "piddle valve" in it. (like a B21-B230 t stat has). Some drill a small 1/8" hole in proper place on the t stat .

Also how is your radiator's condition? 1967 model old? newly replaced or at least cleaned out?

I had it boiled when I got the car three years ago. It's been flushed several times since then. The car runs cooler than it should so I'm not worried about the competence of any of my cooling system parts.

DId you bleed the air out of the coolant system as you poured in the coolant as described in my post above? You might have air trapped in the head. Common deal on B20s when draining/refilling with coolant.

Are you going to SE this year? I can bring them then if you are, or if you need them sooner I'll ship them.

I don't even know what or where SE is. Is that the one in Alabama? Man that's a long drive but I do need to make up for missing Carlisle

How far is that for you?

Yeah my girlfriend does the Instagram thing. Sometimes I find pictures I didn't know she took

I tried to fit some new 5" diameter 350lb. springs yesterday...



but they were too soft and didn't work out...



Threw these on just for laughs. They're 16"s so a little smaller than what I want but it did make me realize how good some RS or any old school BBS would look on the car. The offset is too high also. If they were around 0-10 I'd consider putting tires on them.

Damn! That sucks. Maybe try a higher rate? Did the 5" diameter fit front and back?
