Vortec v L98 Heads?
Disregarding the obvious , weight and manifold choice; which would be the better head in stock form for a budget rebuild on a street 383.
113 L98 heads or Vortec.
The Vortecs seem to get good reviews as far as flow goes , valve sizes are same and chamber size doesn't matter as I have to buy new pistons.Have both heads and don't want to invest in AFRs just yet.

I'm definately not the expert, but when I wanted to convert a remanufactured '87 350 to replace a vortec for my '96 Suburban, the engine builder (Jasper Engines) told me it could be done by using the heads, intake, cam & lifters, timing cover, etc... from the original 96 engine. The tech said that the block was essencially the same (as long as it came with a factory roller cam to begin with).
I never ended up doing the swap, so I can't say if it would have worked in the real world or not.

Meanwhile ,back on the farm, the question was.
What I was judging them by was the flow numbers.
L98 58 cc / 163cc intake. I 196 -E 155 @0.500 lift
Vortec 64 cc /170cc intake. I 239 - E 147 @0.500 lift
Note; Stock LT1 head only flows 214 @0.500.
(http://www.chevyhiperformance.com/te...98/index4.html)
I have both types , AFRs are $3000 in local pesos and I would like to get the engine running with the heads I already own and swap to TFS /AFRs later.

Wouldn't take much at all to make them flow well!
