The big limiter here, guys, is Neil wanting to keep the stock heater boxes. Talk of ANYTHING that makes more hp than the heater boxes can support is a waste of time, hence the combination I proposed above. Neil, if you're not crazy about the Ict's then substitute some 40 (or better yet, 36 mm if you can find them) Webers or Dellortos and away you go.

Any feed back on valve size and heads. The off-road car motors I have are big bore valve heads. Is this needed in the a speedster motor or standard heads in 1776 to 1915 will be okay?

No, big valve heads are not needed in a Speedster (although they do make the whole experience so much more fun! ). An engine with bigger valves (and the appropriate port work) does have the potential to make substantially more power, of course, but the the components in any size engine have to work together to produce the flow and rpm's for said engine to hit a target hp.

A 1776, 1835 or 1915 with the parts I suggested in my above post will be a blast to drive, having 50% or more power than a stock 1600. Most Speedsters weigh about the same as a stock Beetle so that increase in power will be noticed!  I remember 45 years ago building my first performance engine (1641 with most of the same components as I've suggested above) and the difference in my stock '67 Beetle (it had stock size radials) was astounding. And your Speedster would be an absolute hoot with a 2276 (handling and braking upgrades will be required to make it a safe car), but then if you want it to rev much past 4,000 rpm it won't have stock heater boxes, so you have choices to make...
