Are any tuning parts available for the model a 4 bangers? or am i better to use a flathead v8? I think the icm phaeton is next on the bench and I'd like to do a mild hotrod using as much of the kit as possible. I figure building it will give me better comparison pics too

I did a hopped up 4 banger a while back and made a ohv conversion head and made a intake from some scraps. I did a Rajo head because it's a super simple shape, just a rectangle with sheet plastic cut into the shapes of the intake and exhaust flanges. The valve cover is for a Ford 2.3, it just happened  to be the right size and shapes. I looked a bunch of early speed parts until found a few things simple enough I could reproduce them.

I knocked this together a wee while back. It is a Cragar OHV conversion. I milled the rocker cover but a plain one could be easily cobbled together. It is mostly larger sizes of plastic shaped up by hand. The bolt heads are round rod glued into holes drilled into the head. The manifold and tappet cover are from the Revell Model A pickup kit as is the base engine

According to an article written by Tim Boyd, on scale Bangers, the Revell Model A's and the AMT 29 Model A Roadster are the only kit based Banger Engines in Plastic. The OHC Head in the AMT kit is a Vintage Pre WWII  Hop Up piece, and the Parts from the Two Revell Kits are more Post WWII, (1950's) THe AMT parts are simple, and there are only 3 of them, Head, Twin Carbs, and a Racing Style exhaust pipe. The Revell parts are better detailed and there are a few more of them.

I hope these images help.

I've looked online a lot. Returning to my 29 Ford from a couple years back. I couldn't find any example of this type of exhaust being used in 1:1. Do I need to find a lake style header for the 4 banger?

Depending on the exact period, there would have been plenty of cars running 4 independent stacks...probably more prevalent earlier.

Some car builders tended to run everything into one big pipe (mostly to get some of the heat and smell and noise away from the driver)...which could go high or low...but there wasn't any widespread attempt to do "tuned" exhausts with carefully calculated primary pipe lengths and smooth collectors with rotationally-spaced exhaust pulses, etc. until later, i.e. late '50s-early '60s.

The science on the lakes wasn't typically very far advanced, though the principles of exhaust "scavenging" were known, and banger exhausts were usually pretty crude as far as just getting everything into one pipe, sometimes opting for 4-1nto-one or two-into-two-into-one.

AND...any car that would do dual duty as a street ride too would most likely have 4 pipes run together somehow, and running kinda low for ease of running a muffler.

EDIT: This one looks like an attempt at equal-length primary pipes, apparently pre-war, and definitely not street driven.
