Which distributor have you used there? Any modifications to it?

Those are porsche 356 preA heads " 1948-1955 356 preA heads " those heads have the same vw 36hp head stud pattern ..so they will bolt right up to the 36hp case ...the later 1955-65 porsche 356/912 heads have a wider head studs pattern and because of that those later 1955-1965 heads won't fit only preA 356 heads will work with the 36hp case . the only way to make the later 356 heads fit with the 36hp case is if you relocate the 36hp head stud pattern on the case .. to the later 356/912 head stud pattern ...it wouldn't be that hard to do if you can make a magnesium plug to plug up the 36hp head stud holes and than weld the outside of the plug and inside the case basically sandwiching the threaded plug than redrill the case to the later 356/912 head pattern and bore the case for the bigger stock 82.5/83mm cylinders can go even up to 90.5 mm pistons with the later 356/912 pattern/heads ....I've heard a guy used jb weld to plug up his 36hp case and drilled the 356/ 912 pattern much faster to do it that way ...than a plug and welding the magnesium case ..but I think the welding/plug way is much better / stronger than jb weld but to all reach its own ... |

In the very first photo, the engine in the foreground is a Pre-A 356 engine and it does have 356 heads.

| Before putting on the heads do you replace the copper seal gasket like they have on a stock head or is it just cylinder to head, no copper gasket seal? |

No. I don't put any type of copper seal gasket on my engines. Either stock or built.

Joe - these engines look amazing, like normal!  Quick question - what do you usually use to block off the heat riser openings in the rear tin? I see some pics after the engine is all done with openings there, and would've thought they'd be welded closed prior to painting/powdercoating. Just curious what you've done in the past in this area, thanks again for posting these works of art! |

This is absolutely a work of art! The attention to detail and precise assembly is so obvious. Joe definitely sets the high standard for me to hopefully achieve on my Zwitter!

I think you have me confused with another engine builder. I've never left this area open or even worse, welded it up shut. If this area is left open, heat from hot exhaust would come through and possibly overheat the engine. If this area is patch welded shut, it would not let hot air / heat come up BUT......now it does NOT look original! I'm about building these early engines AS ORIGINAL as possible. In all my 45+ years of building the 25hp/36hp engines, I've never patch welded these areas shut but rather fabricated brackets that would hold the heat riser block off plates in place to duplicate the "look" when there were no provisions for mounting them on aftermarket exhaust systems.
In this photo below, you can see this aftermarket exhaust system has NO provisions for mounting any type
of heat riser block off plates. Leaving this area open allows hot exhaust heat rise into the engine compartment...
BELOW: I make a "foot print" out of 1/4" steel and position it exactly where I want the heat riser block off plate to be installed noting
NOT to make contact on any sides of the rear breast plate and possibly burning the powder coated tin. I weld it to the bracket
and attach it to the top exhaust stud.
BELOW: Here you see the beat riser block off plate as installed with gasket. This makes for a clean installation and
still keeping the "original" look of an engine as if it were to be built back in the day........Cheers!

Thanks Joe! I didn't see that in the latest pics with the exhaust on, and that looks really nice! I noticed the exhaust system didn't have the risers so I was curious how you were going to fill those holes, and I know for CERTAIN that you weren't going to let that detail get overlooked.
I noticed the nicely-coated tinwork and still the holes, and the major no-no of leaving holes open and letting hot exhaust into the engine compartment, so that little addition looks like the ticket, thanks! |

Hi Mr.Okrasa,
What is the purpose of the sheet metal fixed between the two air evacuation sheets under the pulley? To limit the heating of the engine block by the exhaust?
Is it homemade or can be find somewhere? Thanks |

This is a "heat shield" that the VW factory used to keep heat from the muffler away from the oil pump. They are used ONLY on early 25hp
engines that have the "tabs" on the heater boxes where they attach. They are available from a vendor here on this site: VIRTANEN.
Cheers.
