Dean, So here is how I remember it. I have used this method since 1972. Best of all done with the engine out so you can actually see the geometry well. First of all this method takes in to account everything that you may have changed on your engine including different cam, lifters, deck

Dean, Be careful with the adjustable rod. I have had some I made myself and I easily bent them...especially with serious valve springs. Whatever adjustable you buy, make sure that the actual ends are the same size and diameter as your pushrods that you will be using. I have seen both

Dean, do live any where near NYC? I would be happy to help. The first thing I would check is the deck height. If this is not correct then you are at risk of damaging your engine as the compression could be too high and would be one explanation for your push rod dilemma. What kind of crank

I am finally installing my rebuilt heads into my 1915 cc engine. I have the heads on, put in the push rods and am test fitting the rocker arms to check geometry. I put the shims that had been installed under the shafts originally and there is not nearly enough room for the swivel foot adjusters.

When I did mine I made an adjustable push rod out of a stock rod. Basically cut one in half, trim down then cut some threads and insert threaded rod with two locking nuts. Install the head torqued to spec. Do not install the push rods or push rod tubes. Install your adjustable push rod

I'm ignorant about both. I could measure the exposed studs. If it would help. I've tried to ask SF for engine details before, but they've been silent. I think I'll contact Rich at RIS; he has been helpful so far. On May 26, 2015 6:10 AM, Daniel Moy sole...@gmail.com wrote: How is the deck

I re-read the info from the machine shop. He thinks the original engine builder, Strictly Foreign, didn't set up the push rod length at all and that I need to do this. That makes sense as they are way off. So who has a good description of measuring proper pushrod length? BTW. RISMachine did the

Guys, Your good old copy of How to hot rod vw's has excellent instructions on this. Although...if you have stock rocker arms and stock pushrods they really should be close. Oh, stroked engine? Cheers, dave On Mon, 25 May 2015, Daniel Moy wrote: When I did mine I made an adjustable push
