R3W7 Assembly
So, tomorrow I take the block in to get bored and honed.
Ordered the remainder of the valvetrain today after talking to Isky. These heads use a 2.00" installed height, so I went with the 9985RAD springs; these are their 'toolroom' steel springs. I used these as I had a few guys tell me they last and last and last. I discussed the pressures of 245/600lbs and Isky said that 600lbs was heavy but not super-heavy. They're using 1000lbs springs pretty commonly now. I should note that even 600lbs is about 200lbs more than recommended by the various Mopar books I have. I mentioned this and they said, "Those guys are 20 years behind the times" lol.
The retainers are their 92-ST, which are also 'toolroom' steel and are only a tiny bit heavier than titanium. I used these as I am not wild about the long term prospects of titanium retainers.
The locks are VL-700, which are their 7 degree chrome moly steel locks. The Isky guys told me 7 degree locks are their top choice; they sell 10 degree locks to stay in the market but their own testing shows 7 degree locks are best. They did qualify this with the usual 'as long as you're not buying junk parts".
Valve pocket locators are Isky 800-VSL; these work on the W7 head with the 1.565" pocket size.
Shim kit #8, 72 shims in 3 different thicknesses will allow me to set the final compressed height where I want it.
Last, Crower .090 deep lash caps.
