Need recommendations for cylinder heads

[J Persons]

Thinking about putting together a Dart 427W shortblock. They come with a 26cc dish piston and will give 9.5 to 1 compression with a 62cc head. I would like to run a 60cc head for a little more compression, and still have enough port volume to feed the 427. Any recommendations on a quality head that meets this criteria? Thx, John

Check out my CNC ported RHS. The flow 335 on the intake and 242 on the exhaust.

I like the Trick Flow heads. Several designs and cc's to match. Pistons do need to be cut for the heads if you have a close chamber or tons of camshaft lift.

Hi John,
For a hydraulic roller lifter 427-W that is limited to 6200-6400 RPM I would use a AFR 205 or Dart 210 heads. If you want to twist it higher then a solid roller is required and then bigger heads, more compression and less reliability. The question you need to ask yourself is how much HP do I need? The RPM you'll operate at and your budget too. A good running streetable 427-W will put out an easy 1.1- 1.35 HP Per cubic inch on pump gas. So you can expect 469HP to 576HP. The 469HP would be very mild, yet plenty of power and up to 576HP and be very reliable.
We keep building engines, dynoing each and proving with real numbers what works and works better.... We're a WD for DART, AFR, Edelbrock, Ford Racing & Trick Flow.

Power comes from cylinder pressure. The more pressure you can build, the more pressure you'll make. If your static compression is only 9.5, in order to keep the pressure up, you'll have to use a fairly "small" cam. That, of course, will limit top end power.

Take a closer look at Gordon's RHS heads. You can get them with a 58cc chamber, and either a 2.02 or 2.08 intake valve. That smaller chamber will bump your pressure up some, and allow for a bigger cam.

Gordon ported a set of Dart heads for me, and they are a work of art. I would call him and discuss your engine plans before spending a nickel. Your intake plans will play a big role in head selection, too.

Personally I would go with Trickflow heads. I built a 408w 2 years ago and with fast as cast with a nice valve job and a Jay allen custom cam It made just north of 600 on the engine dyno.
