Edelbrock or stock heads?
#1
Other than weight savings is there a big benefit for going with edelbrock aluminum heads over refurbishing the stock ones?  If so what are they?  I plan on running a large roller cam I got from a forum member which will require adjustable valve train so there will be an added expense of drilling the stock heads for screw in studs and guide plates.

So what should I do? Big Grin

Thanks!

Go with aluminum heads.....theoretically, you can run more compression with aluminum and the Edelbrock heads should flow better than refurbished factory heads.

Depends on what factory head flows we're talking about. 2V maybe, 4V no.

This debate has been going on for years, about stock versus modified stock, versus a variety of aftermarket heads. Verbal blows have been exchanged on the 351C.net forum over it.

These are a nice cylinder head that make some power but a step under CHI and AFD heads but better than edelbrocks.

My stocks are 4v heads.

These are better heads and almost $300 cheaper per head?

I have my stock heads in for service, as after 12 years of the car sitting in storage, I sprung a head gasket leak. Took the heads in to have them checked out, ugh. Needs new guides, four valves being replaced and milled.

Bottom line is it will be a few more weeks and it's a touch over $1,000

Then mine will be closer to $1500 once I factor in new springs, retainers, studs, guide plates and I would still have the heavy valves.  Those Trick Flows are looking more like the better option.

Wade,
I have the edelbrock heads on a 351c. I am very satisfied with how they perform. The only issue I had with them was after I ate a camshaft after 20K on the motor, I figured I would have the heads checked out while the motor was apart. My engine guy found three tight guides. I spoke with a few other people and found that is common, even right out of the box. Keep in mind my heads are about 10 years old, I am sure they corrected the problem, I hope......
Thanks, Jay

What stock heads do you have?

Got to think of this like baking a cake. You can buy the absolute best ingredients, but if you don’t get the ratios right the cake will fail.

Be sure to buy a combo that will net you a good dynamic compression ratio. Heads/camshaft/pistons/gasket are all parts that need to match up to make you a fine cake.

My current heads are the stock 4v's.  I already have the cam so I am going to build the motor around it.  The motor was rebuilt about 5 years ago but probably has less than 200 miles on it.  I won't know what pistons are in it till I open it up.  If stock pistons can I use them or do they need to be replaced?

Here is the cam.   https://www.summitracing.com/parts/cca-3.../make/ford
