ok, some of you may remember the 408w that I was working on a few months back. The engine only put down 308 rwhp, but it has come to life after attending to a few tuning issues. The engine has edelbrock rpm heads with 1.90 valves (I think). The owner went and bought a set of Victor Jr. heads off eBay, kind of on a whim. Here are the problems.

I am thinking there could be some clearance issues, meaning valve to piston, in the way of the new heads having 2.05 valves. We may have other problems, because I think he may have bought a set of Victor Jr's with 70cc chambers vs the 60 cc chambers. I have the engine build sheet right here, but there is a ton of numbers, so I am only going to provide the ones I feel are essential, unless someone asks for something specific.

351W-1969 block
Pistons - BRC inverted dome with 30cc piston dish
Compression is 9.27
Scat 4.0 crank/eagle 6.200 h-beam rods
Deck height is 9.49, bore is 4.03, and stroke is 4

There are tons more numbers on this sheet and I know some of you guys are great with this stuff. Heck, some of you may be running a combo similar and can help me out. I am not sure on the rocker arms, until I pull a valve cover. I was suppose to begin swapping these heads tonight, but want to hold off until we figure out if they will clear and until I can check part numbers and realize if he bought the bigger cc sized heads.
Thanks guys,
Ryan
