About $20... come with pipe tape already and have a the smmer hex head to

Is this just a stock GM headbolt? Im a service manager at an import dealer and get great prices from other dealers.......so if i can just order through GM that's fantastic...

They recomedn their medium size 986-16 spring.

I use a stock diameter high pressure single spring with similar seat and open specs.

This Summit racing Spring is similar to what I'm using
SUM-174000
Others are Lunati 73943
Isky 235D

Pioneer 810107-4
Pioneer Automotive 810107-4 - SummitRacing.com
You need to order 4 units to get 16 springs
They are packed as a 4 spring set pack.
..

Crower Performance Valve Springs 68304-16

Comp valve spring shim kit #4753 You need this to correctly shim the deep exhaust spring seats
to get the installed height right.

use locked timing and ported vac advance . good match to your carb and intake. and purpose
Do not assume lift clearance on heads (Retainer to seal). Measure it your self.
.507" .510" This cam needs good springs and quality lifters. Works well.
You will like this one in your vette. very strong from 3000 up. Degree it for best results.
You do not need to drop the pan to change the camshaft.

Remove first few oil pan bolts in front of oil pan, loosen a few more.
Just pry the pan down a hair,just enough to slip the timing cover back on, after
trimming the corners of the timing cover.

Be sure the springs are all installed correctly at correct height. 305 head have deeper exhaust spring
seat. requires a .105" (.060+.030+.015) stack of spring shims to correct, when ex rotators are eliminated. 6800+capable with the correct springs. 6000-6400 shift point is plenty.
Cool idle 3.5" or 4.5" power valve., jetting is fine.
The valve train will not be perfectly quiet with this cam. It has fast action and agressive ramps.

It will GLH.
Currently I have comp 981 springs with about a month or 2 run time on them. Will these get the job done or is an upgrade absolutely required.....?

True, but having to pull the Rad, and front of the motor down only to have to do it again would suck....as it is I need to drop the oil pan this time and replace the front cover, never pulled the pan on one of these but indont think there is much in the way?

bygddy Hey f-bird, things got a liitle bit more intresting today, one of the guys I hang out with has changed directions on his 406 build, so he offered me me his XE284 cam and long slot rockers for 200$. They are new in boxes......is this something I can use in my current set up? Heads are good to 550 I'm told according to my machine shop guy after I asked your appropriate measurements. Whether they will flow that is of course another subject....sticking with my welfare build this sounds like a decent deal to me if it will work....the converter i got is the b&m 20413, and 411 gears....and as above the 4779 Carb....power interrupt switch, lock timing at 34-36, 3.5 pv, 70-80 jetting, does this sound like a street slug or something that's actually going to get me the damn 12sec et I want so bad for very little cash? I have no issue shifting the thing at 6500 till it eats itself....assuming the heads flow enough to warrant it.....what's your and anyone else's input?
