Cylinder head

[FARMER]

I've done the search thing and am unable to find an answer to a question I have. I'm bulding a long rod 4.6 low buck stroker. The question is: will a stock head work or do I need to have to go with a roller valve setup?

Stock will work fine.

Not sure what you mean by "roller valve setup" but I guess you're referring to roller rocker arms.
You can use the stock head with stock stamped steel rockers.

no such thing, those use expensive pistons.

I used stock head, cam and lifters with my long rod 4.6L. I would have liked to have ported the head but did not due to time constraints.

I do notice top end falls off past 4200 rpm but low end torque is pretty much amazing.

There is now if you look at my stroker recipes.
A set of Keith Black IC944 pistons costs $416 so that's not much more than the cost of a set of 677CP pistons ($140) plus a set of reconditioned 4.2 rods (average $200 in ebay). Therefore the only reason left for using 4.2 rods in a stroker build these days is if you want to build a close copy of my "low CR rockcrawler" recipe.

Thanks guys, I figured I could use the stock head I just wanted to verify.

It's about $120 for recon rods if you use the ones that came in the 258 core engine you use for your stroker.

[amcinstaller]

or less if you happen to have an old 258 laying around cause your amc or jeep came with one

That's true but then the 258 crank would also cost a lot less.

Well my '75 12cw crank engine was put on the back of my flatbed when I wasn't looking! can't get much cheaper than that! and I sold the rods to Muad'Dib for $40 and he paid just shy of the $120 I posted for the recon of them, so that's about the going rate for a full recon of a set of rods, but if you think your rods are ok to run it could be a lot cheaper.

got my 80 12 cwt the same place as my short rods. wailed a porcupine at 140kmh, popped my oil filter (it was larger for more filter capacity) and the rest is history. cleaned up to 10/10 tho, cant compain.

[amcinstaller]
