1978 318

My brother has a 78 w200 with a 318. Hes wanting more power. I've talked him into ditching the stock 4027593 heads for some aftermarket cast iron ones. What's everyone running on here for after market cast iron heads? The EQ sound nice. Would they perform good with a stock bottom end and a Hughes whiplash camshaft. Were not looking to own the street but it would be nice if the truck would get out of it own way.

318 heads are pretty weak in the flow department, but it depends on the power level your looking for might not need a head swap.

There’s a magazine build where they do a stock 318 and just add 4bbl headers and a comp xe262h cam and get 282hp @ 5000 rpm, where it’s a truck you could drop down to a 256 or 250 with a little loss to top end.
