I am getting going to get ready to put a 2056 FI engine together for a daily driver. Trying to decide if the cost is worth the difference. Biral are supposed to run 20 % cooler. Porsche used them for a couple of years and moved on to coatings.

Good prices at AA.
Does anyone know them? If so could you ask them about doing Biral 103 mm cylinders? The head prices are ridiculous, not even worth doing a set of stock heads at those prices. Good to see this vendor. Rich |

Good to see this vendor. Rich Odd that there is no additional cost on the heads to have them relocate the spark plugs to the 2.0 location. How do the economics of that work? It seems like the welding and re-machining would add some cost. |

I'd venture to say the stock replacement 2.0 heads just have the larger bores for the cylinders and that is all. |

A 4 stud intake Manifold will be required. Heads comes with Stainless Steel 42mm Intake and a Stainless Steel 36mm Exhaust Valves, with Harden Keepers, Chromoly retainers, and Single high rev springs. They are ready to install. Made from an AMC 1.8L type 4 Casting with Breather using 8mm valve stems it is available with both single or dual high rev springs. The heads can also be opened to 103 to accommodate the larger bore sizes. " |
