This is the price I found on the heads:
Any recommendations on a cam?
The truck is a 1985 K10. The engine was swapped from the stock 305 to a 350. I have not ID'd the current engine, though I need to get the casting number. I have not removed the heads to check the code stamping numbers there.
Great choices here.
Incidentally, you do not have to remove the passenger-side cylinder head to get a view of that stamped code, just look down behind the alternator, you will have to clean it with a wire brush.
Don't get too aggressive on that area in case the numbers are lightly stamped, you could obliterate them if not careful.
Lets hope that the replacement engine is a later & newer Hydraulic Roller engine!
Under $600 for two new heads is pretty good, no worries or costly machine work.
You will need correct gaskets, head bolts, valve covers, push rods, good rockers, and other ancillary items.
If the new block is not already a hyd roller motor, but has been factory machined for that, I can recommend the LT4 hot cam with GM Hyd-Rlr lifters for good power and reliability on a budget.
Even though it was designed for the LT4 reverse cooled Corvette, it will work in a properly machined roller lifter type block, you just have to make sure the drive pin is the correct length.
The cam lobes were profiled for LT4 ports which are just a little bit better, but still very close to those Vortec heads in design and flow numbers.
You can buy one of those cam kits for around $600 (alum rckrs incl), but personally, I prefer the Crower Enduro 17-4PH stainless steel roller rockers for virtually every
street performance engine.
