2009-8-13 Re: Issues with using Aluminum heads on Iron Engines. I think My combo is about perfect for my size boat + it was super cheap to build. All parts for just under a grand! Most of it used. Hot cam is spec;ed at 218/228 .525/.525 112 LSA I'm spinning a 21 Laser to 5400 RPMS and a 23 Laser to just about 5100 RPM's with full load.
2006-7-24 I know that when this technology was newer, the cast iron block and aluminum head could be a problem if the engine ever overheated and it warped the head gasket. I know of a friend's parents with a Thunderbird this happened to. However, I don't hear much about this anymore. The Chevy V6s, 3.1, 3.4, 3.5, 3.9 are all cast iron block/aluminum head.
Aluminum heads will not automatically create more power than iron heads unless they flow more air and are installed on a higher compression ratio engine. In cases where you have a decent port job on a set of iron heads it is possible to bolt on a set of out-of-the
2021-11-13 One factor that makes many engines hard to seal today is the use of aluminum cylinder heads on cast iron blocks. Aluminum heads save weight but expand 1.7 times faster than cast iron when they get hot. The difference in expansion rates creates a
2017-5-4 A lot has changed in the performance cylinder head market since my last head story in EB in 2010. First of all, 600hp is the new 500hp, and if a power adder is involved, you'd better be packing 800hp to have any bragging rights at all. Heck, you can now
2016-2-24 Over the years the move has been made from all gray cast iron engines (with even cast iron pistons) (40HP / liter total cylinder capacity) to cast iron cylinder blocks with aluminum heads (50-60 HP/L, to all aluminum engines (cylinder block plus head) up to 80 HP/L (atmospherical engines) Nowadays there is an tendency to switch to nodular cast ...
Most late-model engines have aluminum cylinder heads and cast iron blocks. Aluminum expands and contracts at over twice the rate of cast iron. This creates a lot of back-and-forth scrubbing on both surfaces of the head gasket that can literally tear a gasket

2000-10-25 2004-10-21T13:06. Yes your torque specs will be different with aluminum heads than cast. Aluminum has a higher coefficient of expansion than cast iron. You need to follow the instructions that came with the bolts. For example, I got the ARP head studs and only torqued my heads down to 115 lbs/ft with moly lube.

2016-11-4 It's also called vermicular graphite iron. Ford's block is only about 1/2 CGI, the other half being made out of aluminum. While the CGI provides toughness where it's needed, the aluminum provides strength and stability at a much lower weight penalty.
2015-10-1 Cast-iron versus Aluminum Up through the late 80s and early 90s, the majority of high-output engines were based on cast-iron block designs. Nissan's RB26DETT, Toyota's 2JZ-GTE and Mitsubishi's 4G63 relied upon cast-iron blocks to

2019-8-14 Most performance heads are built with more than sufficient clearance. The one small-block head that has problems in this area is the iron Vortec head. If you are assembling a set of heads from various components and manufacturers, it is best to ensure that the locks and retainers are compatible and that they are matched to the valves.

2010-6-2 Cylinder Sleeves and Liners. Iron sleeves provide a wear-resistant surface for the piston rings, and they don't have to be very thick because they are supported by the surrounding block. Cast iron blocks, by comparison, don't need cylinder sleeves because the iron is hard enough to resist ring wear. If a cylinder is cracked, damaged or worn ...

The heads looked like they have a thick deck and were made pretty good .
