96"/SE204 Combo With A Little Extra ?
Any thoughts on how a 96"/SE204 combo would do with the addition of .030 hg and some mild head clean-up? Big Boyz calculator shows this to be 9.56 static/9.02 corrected and 181ccp. Would the benefits be worth the expense? I can see the motor being more efficient and cooler...

The 204 and 37 with the 37 less sensitive to detonation. However, if you decide to go aftermarket, work the heads and set them up for more compression, say 10.0-10.2 and look at the Andrews 54.

Yeah, wouldn't really know that until the heads are off I guess. Another thought was possibly 54's(with a 4* sprocket) that would allow stock pushrods with the .030 but not with the 204's. They would be better off though with a bit more CR. I do have a new set of SE tapered pushrods to go with the 204's.

Also pay attention when tightening the adjustors if you use the SE tapered pushrods; they have a history of cracking from the inside out. I have had two come loose and won't use them any more without replacing the adjustor nuts.

The stock pushrods should work with the SE204s if all you are doing is relacing the stock head gasket with the thinner .030"; you are only losing about .012" in height. Check the math on the 54s. I believe they may have a different base circle diameter.

You can spend the money to have Bean port your heads but unless you go for bigger inches and serious hi-lift cams, the money would be better spent on fuel management software, pipe and tuning. JMHO.
I was not aware that the MoCo has corrected the adjustor nut problem; that is good news as the pushrods are nice hardware.

As I thought but couldn't remember how much smaller. Like I said, check the math; you may want the adjutables with the 54s to get enough preload on the lifter to compensate for leakdown and valve train clatter. Stock pushrods will work with the SE204s abd will preload the lifters a bit which is not a bad thing.

See what Kirby and/or Bean says but if you are going with the larger valves, you might want to rethink the 204s. A cam that can take advantage of the extra breathing capacity might be a better choice. As for the cleanup/porting, those heads, bone stock, with a good performace valve job, decked for compresson with a .030" head gasket, the Andrews 37 cam with good pipe and tune will make low 100s torque and mid 90s HP in a 95" build. Good luck!
