Roller LA Deck Height

Bobzilla said
Deck height variance and pushrod length have very little to do with valvetrain geometry on an LA Mopar small block using factory rocker arms. The geometry is fixed since the shaft mounting and the size of the rocker arm do not change. The only thing a longer or shorter pushrod will do is set the plunger preload in a hydraulic lifter.

If the rocker arms are changed to any roller tipped rocker arm the geometry will be off and pushrod length will not fix it.

I do not know the actual deck height and the number is considered nominal anyway since factory tolerances allowed a fair amount of variance in the advertised number. This can be measured precisely by the machinist decking the block or roughly with a larger caliper while engine is apart. No real help since yours appears to be assembled already.

Thanks.
Yes mine is assembled, although at the very least I could remove the rocker covers. But I believe with the original rocker shafts and pushrods from the roller block everything should be ok.
I did Prime the engine and put a test pressure gauge on it was reading 65 PSI at 1600 RPM drill speed with 30 weight oil. So I'm thinking that should have pumped up the lifters I turned the crank until I had oil coming out of the rocker shafts on both sides and then turned everything back to zero I was able to rotate the pushrods when the Pistons were at top dead center on compression stroke however there didn't seem much play in the Rockers themselves. Just for consideration.

Curious what effect all machining and such may have.
As stated the block is a roller I'm assuming the deck is shorter than the LA block that had originally came on then the deck was milled .010
And the heads were milled .010 as well so with . 010 off the heads and the deck as well plus 014 shorter deck to begin with that's a total of 034
Not sure if the math is correct.
Thanks again for all the help.
