Hey Guy's I have been thinking of changing my heads on my smallblock stroker. 10.5 to one x block 422 CI engine. with fully ported Eddie heads. The little engine does ok and takes my 3500lb car into the high 10s pretty regulary. Would buying a set of better heads help ? I was leaning toward the 360-1s . I know this is a pretty general question but I am just looking for opinions .I hate to pull it apart and sell the eddies if it won't make a lot of et difference.

The Indy heads will make a good bit more steam then the eddies, but I would just go right to some 59° W9. It cost me $5500 to switch from batton w2s to Indy 245 cnc heads through shady dell. It latter cost me $5000 to switch to w9 heads with Brett Miller doing the cnc job. I did search for some deals but it wasn't that hard. Both included new intakes.

You will see a lot of difference.
I had stage two ported 416 eddie motor, car went 10.74 best ever. Weighed 3350 with me in it. I sold the top end, and swapped on a w5 top end. Same exact short block/ cam etc.. Ran 10.38 first time out the next year.
I ultimately got those W5 heads in the 9.80's, on a different shortblock.
There will be a lot of difference. An eddie is a very "small" head for a 420 inch motor.
The Indy and W5 have similar potential.

That is what I was thinking. I know my engine makes a lot of torque but it has never ran like I thought it should. I have an old roller cam 650 lift set up for a 13.1 stock bore 340 in the car now. So w9s or 5s will make that kind of difference ?? Thanks

Both the Edelbrock and Indy heads will work. I've gone 9.73@135mph with Edelbrocks and 9.66@137mph with Indy heads so far. BOTH combos have more in them.

I agree 100% on torque. Hopefully I can get that big azz boat of mine moving a little better with the head change !!

Thanks, Guys Sit down with a sheet of paper and start writing down the cost of switching over to W series heads and it may scare you. Start a post to see what all is required from probably pistons, pushrods, intake, heads, rockers, and who know what else.

But I guess I would need a race block first. I am still running a stock 340 block.

I lost 52 pounds so far since late April trying to make up for my 130 pound heavier R3 block How do you figure 130# more than a stock block... my car with a 395ci to my 405ci W-9 R-3 block with a dry sump was 18# heavier... and thats dry sump over a wet sump.. and that engine had more braided line by far.. but the 395ci was a W-2 head.... but when it rolled over the scale it ended up 18# heavier

I know it's way more than 18 pounds heavier but I thought for sure it said 130 pounds in my building big inch small block book. I hope it's not that much but hopefully I make it to Norwalk so I can weigh it again

That looks like a killer deal on the heads and intake. I have to put my stuff up for sale soon.
