I was looking for 4 years for some 38 Trons and could not find them (seem to be a very popular size) My motor guy said the 40's would work best on a hot humid day which is no issue in the Summer. I was originally going to build a 1197 motor as it would have been a better match for the head but a low dollar big block came up that already had a 1327 kit in it.
I am kick starting mine with a retard on the timing plate.
Is it a ideal combo - No, but it will get me down the track just the same.
Matching component sizing is easier when your not constrained by what is available on the cheap.
There are guys around here that bracket race with $30K into the motor.
I am almost finished building this bike, I bought it as a roller without a engine. I built the engine on my own.
It is a small tire bike, 7" slick. It has a full custom frame and supposedly weighs 350 LBS fully built.
The PO had timing slips that showed 9.20's with a 1075 motor. I was told the original builder had run as fast as 8.60 with a alcohol injected 1327.
I have a local guy who does all my motor work so he helped source some parts, did a valve job on the head and finish porting it sized for the cams. He also welded and trued the crank for me, not up to Pearson standards but pretty close. I am running hand clutch, undercut 5 speed... Its just a play bike, Test N Tune night type build.

Here are the suggested combinations :
kzzone.com/kits.html
kzzone.com/heads.html
kzzone.com/cams.html
If you have a stock head you might consider building off what you have as obtaining a used one might take a while.

I started my project with a used KZ street head that already had 37/31 valves and a decent port job.
I bought bigger cams then cleared the head and cover for those cams on my own, had my motor guy sink the seats to make the different cam base circles work and maintain a good valve to valve distance. He then did some more porting that the head was lacking to go drag racing. The head was flycut by me and I assembled it with 520 springs after checking the installed height spring pressure. I also upgraded it with M8 exhaust studs.
Maybe it sounds like a lot of work but it really was not all that bad.
The used head cost me $150, cams cost $200, valve job/porting $150, shim under parts $40, springs $60 = $600
